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.
