Abstract

Abstract

In order to obtain high power all-fiber mid-IR supercontinuum source, the fluoride fiber is pumped by homemade erbium-doped mode-locked fiber laser after two amplifiers to 1.67 W. The supercontinuum from 1 000 nm to 2 400 nm is obtained. The spectrum of the supercontinuum is gradually broadening with the increase of the pump laser power. The output power and the conversion efficiency are 1.21 W and 72% respectively. Experimental results show that supercontinuum has a strong spectrum modulation, and the power spectrum density decreases to 0 mW/nm at certain spectrum points which does not depend on pump power.
