摘　　要：We reported an efficient diode pumped Nd∶YVO4 1 064 nm laser passively mode-locked and Q-switched by a semiconductor saturable absorber mirror(SESAM). At the incident pump power of 7.5 W, 2.81 W average output power was obtained during stable CW mode locking with a repetition rate of 111 MHz. The optical conversion efficiency was 37.5%, and the slope efficiency was 39%. So far as we know, this is the highest optical-optical conversion efficiency with a SESAM at home.We reported an efficient diode pumped Nd ： YVO4 1 064 nm laser passively mode-locked and Qswitched by a semiconductor saturable absorber mirror（SESAM）.
