35 W high power all fiber supercontinuum generation in PCF with picosecond MOPA laser

摘要

We demonstrate 35 W high power all fiber supercontinuum generation by pumping photonic crystal fiber (PCF) with a 57.7 W picosecond fiber MOPA. The picosecond fiber MOPA pumped supercontinuum source exhibits an optical-to-optical conversion efficiency of up to 61.7percent, covering a spectral range from 600 nm to beyond 1700 nm. The compact and practical configuration of this supercontinuum source has potential to achieve higher power scale together with perfect continuum spectrum.
