摘要

光纤激光器的输出功率达到一定阈值后, 激光器中会出现模式不稳定效应, 该效应会对激光器的输出功率和光束质量造成严重影响, 限制了大功率激光器的进一步应用。研究大功率光纤激光器中的模式不稳定机理及抑制方法, 这对光纤激光器输出功率的进一步提高具有重要意义。系统介绍了模式不稳定机理, 并总结了一些模式不稳定的抑制方法。

Abstract

Mode instability effect occurs when the output power of a fiber laser reaches a certain threshold, and it results in serious influence on output power and beam quality, so that the applications of high power fiber lasers are restricted. It is meaningful to study mode instability mechanism and suppression methods for the further improvement of output power of high power fiber lasers. The mechanism of mode instability is systematically introduced, and some suppression methods are summarized.
