摘要：
The saturable absorption characteristics of two-dimensional materials tin disulfide (SnS2) near 1.6 mu m was studied and a passively Q-switched Er:YAG laser at 1645nm based on a home-made titanium disulfide was realized. Under an absorbed pump power of 1075 W, a maximum average output power of 1.42 W was achieved with a pulse duration of 1 mu s at a repetition rate of 43 kHz, corresponding to a pulse energy of 33.02 mu J.
