Paper Abstract

The reflection-type MoS2 saturable absorber was prepared by the spin coating method. The silver plated reflector was made by plating the sliver reflective film on a Hydrophilic treated quartz sheet. The Tm,Ho:LiLuF4 all solid-state laser with MoS2 reflective saturable absorber is realized in Q-switched mode-locking operation. The laser maximum output power is 156 mW, typical Q-switched pulse envelope repetition frequency is 10KHz and the pulse width about 200μs. The repetition frequency of the mode-locked pulse sequence is 100 MHz and the modulation depth is close to 100%. The results show that the reflective MoS2 material can be used as a saturable absorber for all solid-state lasers in 2μm band.
