34W, GHZ repitition rate supercontinuum generation based on tunable actively mode-locked fiber laser

Abstract

We report on the experimental demonstration of an all-fiber high power supercontinuum (SC) source. The SC generation is achieved in a piece of high nonlinearity photonic crystal fiber (PCF) which is pumped by an actively harmonic mode-locked picoseconds fiber laser. It can produce pulses with duration of 8 ps at 1.1037 GHz repetition rate with a central wavelength of 1059 nm and provide average output power of 20 mW. After four-stage power amplifier, the laser average power is amplified to 79.1 W. By launching the maximum average power laser into the PCF, we get an average power up to 34 W in a SC extending from around 570 nm to beyond 1700 nm with a 1048 nm 10 dB flatness.We report on the experimental demonstration of an all-fiber high power supercontinuum (SC) source.
