Pulse width adjustable fiber laser marking machine advantage

Pulse width adjustable fiber laser marking machine advantage. The laser marking machine uses a laser beam to mark permanent surfaces on a variety of different materials. The effect of marking is to expose deep materials through evaporation of surface substances. Thus engraving exquisite patterns, trademarks and characters.

Laser marking machines are mainly divide into CO2 laser marking machines, semiconductor laser marking machines, and fiber laser marking machines. And YAG laser marking machine. The current laser marking machine is mainly use in some occasions requiring more precise and higher precision.

Used in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tool accessories, precision equipment, glasses and watches, jewelry, auto parts, plastic buttons, building materials, PVC pipe.
Then, the fiber laser marking machine is a laser marking machine using a fiber laser. Fiber lasers have become a hot topic in laser physics research in recent years. And it is unanimously recognize as a new generation of products that are likely to completely replace solid-state lasers.

A fiber laser refers to a laser using a rare earth-doped glass fiber as a gain medium. The fiber laser can develop on the basis of a fiber amplifier: under the action of pump light, a high power density is easily form in the fiber, resulting in laser of the laser working substance.

The energy level “particle number inversion” can form a laser oscillation output when a positive feedback loop (constituting a resonant cavity) is appropriately add.

 

                 What is the pulse width adjustable? First we need to know what is the pulse width.

Then, pulse width is the duration of a pulse. That is to say how long the duration of a pulse can adjust. Pulse width: Pulse width is the duration of a single pulse. Therefore, it is a unit of time measurement in milliseconds (ms), microseconds (us), nanoseconds (ns), and picoseconds (ps) , femtosecond (fs) . And other orders of magnitude. The smaller the magnitude, the shorter the duration of the laser action.

 

The difference between pulsed laser and continuous laser: the fiber laser marking machine uses a pulsed laser. Generally the pulse width is fix. However, the fixed-width fiber laser marking machine cannot make black alumina. And the fiber-optic laser marking machine with adjustable pulse width can be easily done. This is an example in terms of applications. Because of the increased pulse width, the fiber laser marking machine has become more widely used.
Nowadays, the most widely used fiber-optic laser marking machine is the black mark on the anodized aluminum, because the general fiber laser marking machine can’t do this.
In short, the pulse width tunable fiber laser marking machine has a wider application range. And is more practical than the ordinary fiber laser marking machine. Of course, the price is also more expensive. You can choose according to your own products and processing requirements.
