Femtosecond mode-locked holmium fiber laser pumped by semiconductor disk laser

Opt Lett. 2012 May 1;37(9):1448-50. doi: 10.1364/OL.37.001448.

Abstract

We report on a 2085 nm holmium-doped silica fiber laser passively mode-locked by semiconductor saturable absorber mirror and carbon nanotube absorber. The laser, pumped by a 1.16 μm semiconductor disk laser, produces 890 femtosecond pulses with the average power of 46 mW and the repetition rate of 15.7 MHz.
