激光光学 模式不稳定 热效应 电致伸缩 非线性效应 laser optics modal instability thermal effects electrostriction effects nonlinear effects
摘要
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。
Abstract
The research status of traditional dynamic thermally-induced modal instability in fiber lasers is introduced, and the theoretical predictions of quasi-static modal instability since 2016 are also introduced. Then, the status of non-thermally-induced modal instability, including electrostriction effects and nonlinear effects in modal instability, is introduced. Finally, the power scaling limit of modal instability on high power fiber amplifier is summarized and analyzed.
