Fiber laser refers to a laser that uses rare earth-doped glass fiber as the gain medium. So, fiber lasers can develop on the basis of fiber amplifiers. Under the action of pump light. High power density is easily formed in the optical fiber. Which causes the “laser number inversion” of the laser energy level of the laser working material pair. So, the laser oscillation output can be formed by appropriately adding a positive feedback loop (forming a resonant cavity). So, including laser fiber communication. Laser space long-distance communication, industrial shipbuilding. Automobile manufacturing; Laser engraving, laser marking, laser cutting, printing rolls, metal non-metal drilling/cutting/welding/(copper Welding, quenching water, cladding and deep welding), military defense security, medical equipment and equipment, large-scale infrastructure, etc.

As the representative of the third generation laser technology, so fiber laser has the following advantages:

1) So, the low manufacturing cost of glass fiber, the mature technology and the compactness brought by the flexibility of the fiber, the advantages of intensive;

2) The glass fiber does not require strict phase matching for the incident pump light like crystals. This is due to the wider absorption band due to the non-uniform broadening caused by the Stark split of the glass matrix.

3) So, the optical fiber material has an extremely low volume to area ratio, fast heat dissipation, low loss, and low laser threshold.

4) The output laser has many wavelengths. So, this is because the energy level of rare earth ions is very rich. There are many types of rare earth ions in the machine.

5) The adjustability is good, thanks to the wide energy level of rare earth ions and the wide fluorescence spectrum of glass fiber.

6) Because there is no optical lens in the resonant cavity of the fiber laser, and it has the advantages of no adjustment, maintenance, and high stability, which is unmatched by traditional lasers.

7)So, fiber export, the laser can easily handle all kinds of multi-dimensional arbitrary space processing applications, making the design of mechanical systems very simple.

8) Ability to work in harsh working environments, with high tolerance to dust, vibration, shock, humidity, and temperature.

9) No need for thermoelectric cooling and water cooling, just simple air cooling.

10) It has high electro-optical efficiency, and its comprehensive electro-optical efficiency is as high as more than 20%, which can greatly save power consumption during operation and save operating costs.
