首先介绍了光纤激光中传统的热致动态模式不稳定的研究现状,然后重点介绍了2016年以来理论预测的准静态模式不稳定;接着,对非热致模式不稳定的研究现状进行介绍,包括电致伸缩模式不稳定和非线性效应与模式不稳定之间的关系。最后,对模式不稳定对高功率光纤放大器的功率限制进行了总结和分析。
First of all, the research status of the traditional thermally induced dynamic mode instability in fiber lasers is introduced. Then, the quasi-static mode instability predicted theoretically since 2016 is mainly introduced. Then, the research status of non-thermal induced mode instability is introduced, including The relationship between electrostrictive mode instability and non-linear effects and mode instability. Finally, the power limitations of the high power fiber amplifier are summarized and analyzed for the mode instability.
