Mitigating transverse mode instability in fiber laser oscillator by employing direct pump modulation

Mitigating transverse mode instability in fiber laser oscillator by employing direct pump modulation

The transverse mode instability (TMI) is a thermal-optical effect, inducing a sudden deterioration of beam quality and average power. This non-linear effect will greatly limit the power scaling of fiber lasers. We demonstrate a direct pump modulation to mitigate TMI in a 30 μm-core-diameter all-fibe...
