✦ Synopsis

A diode-pumped passively Q-switching mode-locked Nd:Gd0.5Y0.5VO4 laser at 1.34 μm using V 3+ :YAG as the saturable absorber has been demonstrated for the first time to the best of our knowledge. At the pump power of 7 W, the maximum average output power of 0.83 W and Q-switched pulse repetition rate of 140 kHz were obtained with absorber's initial transmission of 96%, with the corresponding Q-switched pulse energy estimated to be 6 μJ. The duration of mode-locked pulse within Q-switched envelop was estimated to be 750 ps with 333.3 MHz repetition rate. Output power, W 1.0 0.5 0 1.5 2.0 2.
