The reflection-type MoS2 saturable absorber was prepared by the spin coating method. The silver plated reflector wasmade by plating the sliver reflective film on a Hydrophilic treated quartz sheet. The Tm,Ho:LiLuF4 all solid-state laserwith MoS2 reflective saturable absorber is realized in Q-switched mode-locking operation. The laser maximum outputpower 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 2μmband.
