Abstract

We propose a diode end-pumped passively mode-locked Nd:Gd_0.42Y_0.58VO₄ (Nd:GdYVO₄) laser at 1064 nm using a GaAs absorber grown at low temperature as the output coupler. Stable continuous-wave (CW) mode locking with a 5.1-ps pulse duration at a repetition rate of 113 MHz is obtained. The maximum average output power is 2.29 W at the incident pump power of 12 W with the slope efficiency of about 24.8%.
