Abstract

We report on the first Raman laser based on a fluoride glass optical fiber. The Raman fiber laser was pumped by a 9.6 W Tm 3 + :silica CW fiber laser operating at a wavelength of 1940 nm . A maximum output power of 580 mW was measured at 2185.1 nm , corresponding to a frequency shift of 579 cm 1 ( 17.37 THz ). We observed a threshold power of 3.8 W and a low power slope efficiency of 29% with respect to the launched pump power. Using those results and the known fiber parameters, we estimated a Raman gain peak value of 3.52 * 10 14 m / W , which is lower than the previously reported values.
