Passively mode-locked Nd:GdVO₄ laser at 912nm

This paper demonstrates the passively mode-locked Nd:GdVO₄ laser operating on the ⁴F_3/2--^4I_9/2 transition at 912 nm by using a semiconductor saturable-absorber mirror for passive mode locking, stable continuous wave mode-locked 912 nm laser was achieved with a repetition rate of 176 MHz. At the incident pump power of 17.7 W, 22.6 mW average output power of stable mode-locked laser was obtained with a slope efficiency of 0.3%.
