Advantages and Disadvantages of Fiber Lasers

Fiber laser  advantages : (1) The advantages of miniaturization and intensification brought about by the low manufacturing cost of glass optical fiber, mature technology and the availability of optical fiber; (2) The glass fiber does not require strict phase matching of the incident pump light like a crystal, which is due to the non-uniform broadening caused by the splitting of the glass matrix Stark, resulting in a wide absorption band; (3) The glass material has a very low volume-to-area ratio, and the heat dissipation is fast and the loss is low, so the up-conversion efficiency is high and the laser threshold is low; (4) The output laser has many wavelengths: this is because the rare earth ion energy level is very rich and there are many kinds of rare earth ions; (5) Tunability: Since the rare earth ion energy level is wide and the fluorescence spectrum of the glass fiber is wide. (6) Since there is no optical lens in the cavity of the fiber laser, it has the ad
