Advantages Of Fiber Lasers

As a representative of the third generation laser technology, fiber laser has the following advantages:
1. The advantages of miniaturization and intensification brought about by the low manufacturing cost of glass optical fiber, mature technology and the windability of optical fiber;
2. The glass fiber does not need the strict phase matching of the incident pump light like the crystal, which is due to the wide absorption band caused by the non-uniform broadening caused by the Stark splitting of the glass matrix;
3. The glass material has an extremely low volume-to-area ratio, fast heat dissipation and low loss, so the conversion efficiency is high and the laser threshold is low;
4. The output laser has many wavelengths: this is because the energy levels of rare earth ions are very rich and there are many types of rare earth ions;
5. Tunability: Due to the wide energy level of rare earth ions and the wide fluorescence spectrum of glass optical fiber.
6. Since there is no optical lens in the resonant cavity of the fiber laser, it has the advantages of no adjustment, no maintenance, and high stability, which is unmatched by traditional lasers.
7. The fiber is exported, so that the laser can easily be used for various multi-dimensional arbitrary space processing applications, making the design of the mechanical system very simple.
8. Competent for harsh working environments, with high tolerance to dust, vibration, impact, humidity and temperature.
9. No need for thermoelectric cooling and water cooling, only simple air cooling.
10. High electro-optic efficiency: the comprehensive electro-optic efficiency is as high as more than 20%, which greatly saves power consumption during work and saves operating costs.
11. High power, commercial fiber lasers are six kilowatts.
