5 W Supercontinuum Generation at 1.9-2.5 μm from a Tm-Doped All-Fiber MOPA Laser

Abstract

We report a simple method of generating flat-top high power (5W) supercontinuum from an all-silica-fiber Tm-MOPA laser emitting in the interesting for applications 1.96-2.48 μm range (at -5 dB level), covering transparency window of atmosphere.
