  • MOPA technology and Q-switching technology-Teresa

    MOPA technology and Q-switching technology

    MOPA technology and Q-switching technology are the mainstream pulse fibe lasers in the market.

    However, before 2014, the domestic pulsed fiber laser market was almost monopolized by IPG, SPI and other companies. Since 2014, domestic products such as Shenzhen JPT, Max and other companies have been successfully developed and put into the market. Gradually occupied part of the market share.

    As a more advanced laser technology, what are the main differences between MOPA technology and Q-switching technology?

    The difference between fiber lasers

    At present,  MOPA technology and Q-switching technology are the mainstream pulse output fiber lasers in the market.

    Q-switching technology

    Q-switching fiber laser mainly achieve the power output through a fiber-optic acousto-optic Q-switch (AO). Or as a seed source laser and then through the power amplification

    The laser cavity length is long. The pulse width of the output laser is wide. The pulse waveform is difficult to narrow during the amplification process. And the pulse width and the repetition frequency are correlated with each other. The pulse width is generally about 100 ns. And the repetition frequency can be tens of kHz. The single pulse energy is large. Therefore, it has certain advantages in marking metal materials.

    MOPA technology

    MOPA lasers generally use direct pulse modulation semiconductor laser LD as a seed source. Low power LD can easily modulate output parameters directly by driving current. Such as repetition frequency, pulse width, pulse waveform, etc.It achieves power output through optical pulse amplifier. Meanwhile not changes the basic characteristics of the seed laser.

    Therefore, the main feature of the MOPA laser is that the pulse width and repetition frequency are independently adjustable. The pulse waveform can be flexibly modulated by the electrical signal. The pulse width adjustment range is large. Generally between 1-400 ns. What’s more, the repetition frequency adjustment range is 1-2 MHz. It can realize peak power output of up to several tens of kW. It has advantages in the black marking on anodized aluminum and color marking on ss.

    In addition, due to the different mechanisms of pulse output, Q-switched lasers are slow on the rising edge of the pulse and cannot modulate. The first few pulses are not available. MOPA fiber lasers use electrical signal modulation, pulse alignment, first pulse Available, with unique applications in some special occasions.

    Summary and outlook

    MOPA fiber laser has independent pulse width and frequency. It also has a wide range of adjustment parameters. Therefore, the processing is fine and the thermal effect is low. It is professional in black marking on anodized aluminum and color marking on ss. While Q-switched fiber lasers cannot achieve the effect. The Q-switched fiber laser has strong marking force. And also has advantages in deep engraving metal.

    XT laser take you to know about laser of the fiber laser marker

    We have been discussing the cost of fiber laser marker: why the price gap is so large; how long about its lifetime, and so .

    These problems are not only the concerns of laser equipment manufacturers, but also the problems customers want to know.

    The determinants of these problems often have a lot to do with lasers.

    XT laser meets your curiosity and takes you to know about the internal structure of the laser.

    The structure of the laser of the fiber laser marking machine is the same as that of the fiber laser marker.

    The inside is not mysterious and full of unknown unreliable dangers.

    It is undeniable that it is a product of wisdom under highly civilized conditions and belongs to high-tech derivatives.

    At the same time, its technical threshold is higher than that of fiber laser marking machine.

    And it has higher requirements for objective conditions of employees, environment and tools.

    This also increases the curiosity of the laser of the fiber laser marking machine.

    And many of the practitioners of the fiber laser marking machine have never seen the internal structure of the laser, let alone the customer?

    The internal structure of the laser of the fiber laser marker is as follows:

    laser marking machine

    1.Main parts of fiber laser marker

    The module of the laser includes LED, AOS, Q-light, PCB circuit board, fan, heat-dissipation module, optical fiber, temperature feedback control measurement module, beam expansion module, transmission fiber, etc.,

    There just to satisfy everyone’s curiosity.

    Do not do any technical discussion.

    From the module in the above figure, we can understand that even if the power of the laser is attenuated.

    Or if it is damaged for some reason, some of the modules need to be replaced or repaired.

    In fact, it is the same as the desktop computer we are repairing and assembling.

    However, no matter how the insurance is over, there are always some maintenance costs.

    So the customer needs special protection during the use, especially in the harsh environmental conditions.

    It is necessary to strengthen the protection, such as sand, dust, overheating, etc.

    Regular maintenance, and the fiber is easy to break,we need protect it during the movement process,

    Especially the hand-held or split-type fiber laser marking machine, need to pay attention.

    In the internal structure of the laser of the fiber laser marking machine, each module has its own unique functions.

    We integrate then to realize the transmission of high-energy beams, and the processing of materials through optical devices such as galvanometers and lenses.

    In addition, there are some differences in the structure of lasers from different manufacturers, the functions are similar.

    They are also important factors that determines the price, life and stability of fiber laser marking machines.

  • Mopa fiber laser marker for color marking on stainless steel – Alex

    What is Mopa fiber laser marker

    The most popular way of achieving power scalability is the “MOPA” (Master Oscillator Power Amplifier) approach. The “MO” produces a highly coherent beam, and an optical “A” is used to increase the power of the beam while preserving its main properties. The “MO” has no need to be powerful, and has no need to operate at high efficiency because the efficiency is determined mainly by the “PA”. The combination of several laser amplifiers seeded by a common “MO” is essential concept of the High Power Laser Energy Research Facility. This is mopa fiber laser marker machine

    Different between Mopa laser with Q-switched laser

    Now Q-switched fiber laser marking machine is the most popular fiber laser marking solution in market. We use mopa fiber laser marker  on more and more fields. But also it have limited on some special material, such as stainless steel, anodised aluminium, plastic etc.  In order to recover the deficiencies of Q-switched fiber laser marking machine, we make new mopa fiber laser source. 

    Compared with Q-switched fiber laser source, Mopa laser’s have adjustable pulse. so it have more wide application then Q-switched laser.

    What we can do with Mopa laser

    • color marking on stainless steel

    With mopa fiber laser marking machine, we can do many beautiful color on stainless steel, such as red, blue, pink, green etc.

    Q-switched fiber laser marking machine can only do ordinary marking on anodised aluminium. With mopa fiber laser marking machine we can do black marking on anodised aluminium easily.

  • How to find focus for fiber laser marker – Alex

    Fiber laser marker is become more and more popular in various fields because its price become more and more low. Fiber laser markers is very easy on operation, but for some people who have poor experience on laser machine. They may face many small questions or doubt. specially on focus lens, many people don’t know how to find the focus.

    Why need find Fiber Laser Marker Focus?

    Fiber laser marking machine need through F-theta lens adjust working size. The F-theta lens is one convex lens, like a magnifyinglens. We know it have focus length from lens to pieces. With this length, all light power focus on one point and have very high power. Fiber laser marking machine use this theory focus all laser in one point, then the laser will leave marks after high temperature. 

    So only when machine on correct focus, laser marking machine works well. This is why we need find correct focus before use laser machine.

    How to Find Fiber Laser Markers Focus

    Now total have three ways can help us find the correct focus.

      • In the beginning, we need look for focus manually. We can put one small metal piece on working area and select “Continue” button. Then we need up and down the laser marking head and check the laser light. When there is very strong laser light works on the metal surface, it is the focus. This way the the most common way and easy to learn.
      • Measure the length. Different working size F-theta lens have special focus length. We can measure the length from F-theta lens to working piece. This way have some problems as the measurement may have some error. Still we need do some fine adjustment after find the focus by this way.
      • Outside red pointer. We install one extra red pointer under laser marking head. so when machine open there is two point. When the two point coincide together it is the correct focus. Now we install it for all our machine. When clients use out customers, it can save many times for users.

  • How to select a reasonable fiber laser marker – Alex

    Nowadays, more and more customers are planning to buy a fiber laser marker.

    Not only do they require the machine quality,but also the machine price.

    In a word, they want to choose one machine which are both high quality and reasonable price.

    But how to choose a reasonable fiber lase marker?

    Here I will give u some advises.

    1.The most important part of fiber laser marker

    As in known to all, the laser source is the most important part of the machine.

    Choosing a good laser source decides the using time of the machine.

    Most of the customers would choose the IPG, Germany brand, cause the quality is excellent.

    However, the price is also high very much.

    We often introduce the Raycus laser source to them, which maybe strange to some customers.

    XTL-FP series optical fiber laser marker use 1064 nm Raycus as the sources are used to pump.

    And the average working hours can up to 100000 hours.

    Small and exquisite Volume , applicable in the bad environment

    Optical fiber surface area/volume ratio is high, also good cooling effect.

    There is no need huge water cooling system, just simple air cooling, can be running in bad conditions.

    For example, high impact, high vibration, high temperature, dirt under the conditions of the normal operation.

    The raycus laser source is the best brand in China, we have introduced it to many customers.

    It is both with low price and high quality.

    Therefore, if customer’s budget is limited, Raycus would be a better choice.

     

    2.The power requirement of the machine

    It is known to all that there are many different powers of the machine, such as 20/30/50, etc.

    The bigger the power is, the higher the price would be.

    If the customer only need want to mark on the surface,20w with raycus laser source is enough.

    If they want to depth, maybe choose 30w or 50w, or even higher.

    It depends their requirements, different depth needs different power.

  • Enhance Marking Speed of Metal Laser Marking Machine – Alex

    How to enhance the marking speed of metal laser marking machine

    Firstly, the major factors are laser frequency, laser spot mode and beam divergence angle, laser power, reasonable optical shaping with the processing of auxiliary gas, material. Internal factors mainly in the early models when the allocation of attention, should follow the advice of laser engineers to buy. Another factor mainly requires customers to pay attention to the processing. It is mainly for the marking density, format, depth and laser spot size in metal laser marking machine.

    1. Marking  density

    In the same format, the same spot, the same depth of the case, the higher the density of marking, the corresponding marking speed will be slower, the reason for the density directly increase the marking area in metal laser marking machine.

    2. Marking the format

    Because the large format marking galvanometer deflection area increased, so large format marking speed than the small format marking speed is slower.

    3. Marking depth

    According to the demand, if the depth of the marking to deepen the need for fiber laser marking machine parameters to adjust the fiber laser marking machine power, current and other factors, so in these processes will affect the marking speed.

    4. Laser spot size

    The smaller the spot, the smaller the marking volume, so the bigger the spot, the faster the marking

    4. Setting the appropriate delay

    Different fill types are affected by different delays. Reducing the delay associated with the fill type can improve the marking efficiency.
    Firstly, Arch fill, shape fill. Mainly affected by the corner delay. You can reduce the opening delay, off the light delay, the end of the delay.
    Secondly, Bidirectional filling, one-way filling. Mainly by the opening delay, light delay delay. It can reduce the corner delay, the end of the delay.
    Note: thick graphics, fonts affected by the delay is small, can be appropriate to reduce the delay. Fine graphics, fonts affected by the delay, you can increase the delay.

  • What is the suitable fiber laser marker?-Angelina

    What is the suitable fiber laser marker?

    Nowadays, more and more fiber laser marker appear in the market.

    To meet with the different requirements of different customer, the supplier designed more and more model.

    Then in this passage we would like to take the enclosed type marking machine for example.

    And different with some Asian  customers, the European customer prefer the enclosed type machine.

    The customers from those area, such as Australia,Germany, have high requirement on the security.

    Under this situation, the supplier designed the enclosed fiber laser marker.

    fiber laser marking machine

    Actually this type machine is popular in the European market.

    First if all, it is beautiful in appearance.

    Secondly, it could protect the customer from the radiation.

    However, this type machine could only be installed with the max 200*200mm lens.

    It is cannot install with the 300*300 mm lens.

    Therefore, if the customer has big size products for marking, this type fiber laser marker is not a good choice.

    In this situation, our XT designed a new type machine which could be installed the 300*300mm lens.

    This type machine is also enclosed type fiber laser marking machine, but bigger in size.

    fiber laser marking machine

    For this type machine, it is our new design.

    It is popular in the market, most of our customers like it very much.

    We sold one on site.

    For this model, to make sure the best marking outcome, it is better that the thickness of products do not exceed 50mm.
