光纤激光器以其结构紧凑、转换效率高、易散热和光束质量好等优点正逐渐成为高功率全固态激光器的主要选择。目前,单根光纤激光器的输出功率已经超过千瓦量级,但是由于受受激拉曼散射(SRS)和受激布里渊散射(SBS)等非线性效应的影响,单根光纤激光器的最终输出功率还是受到限制。
Fiber lasers are becoming the main choice of high power all-solid-state lasers because of their compact structure, high conversion efficiency, easy heat dissipation and good beam quality. At present, the output power of a single fiber laser has exceeded the kilowatt level, but the final output of a single fiber laser due to nonlinear effects such as stimulated Raman scattering (SRS) and stimulated Brillouin scattering (SBS) Power is still limited.
