Diode-pumped mode-locked femtosecond Tm:CLNGG disordered crystal laser

Opt Lett. 2012 Apr 15;37(8):1376-8. doi: 10.1364/OL.37.001376.

Abstract

A diode-end-pumped passively mode-locked femtosecond Tm-doped calcium lithium niobium gallium garnet (Tm:CLNGG) disordered crystal laser was demonstrated for the first time to our knowledge. With a 790 nm laser diode pumping, stable CW mode-locking operation was obtained by using a semiconductor saturable absorber mirror. The disordered crystal laser generated mode-locked pulses as short as 479 fs, with an average output power of 288 mW, and repetition rate of 99 MHz in 2 μm spectral region.
