2021年3月6-11日に開催された Photonics West 2021 Digital Forum にて技術部・西浦が「デュアルバンドフィルタを用いたモード同期全PM-NALMファイバレーザ」について発表を行いました。

【Title】
【Abstract】
We report superiorities of a NALM-based all-PM fiber laser incorporating dual-bandpass filter instead of ordinal single narrow bandpass filter. The fiber laser starts mode-locking quickly with relatively low pump powers. Shorter wavelength bandpass window component of dual-BPF is used for inducing Q-switched mode-locking and enlarging amplitude noise. Longer wavelength bandpass window component is used for keeping CW mode-locking. Once the laser starts mode-locking at longer wavelength window, spectrum components in shorter wavelength window are negligible. The laser produces various of ultra-fast pulses by adjusting longer wavelength window property.
