ResumoWe demonstrated passively Q-switched mode-locking in a laser-diode pumped c-cut Nd:GdVO4 laser with a Cr4+:YAG crystal as the intracavity saturable absorber. At a pump power of 17.3 W, the Q-switched envelope repetition rate was 37 kHz with the maximum average output power of 2.1 W, while the mode-locked pulses within the Q-switched envelope had a repetition rate of 143 MHz. Experimental comparison between c-cut and a-cut Nd:GdVO4 lasers indicated that the c-cut Nd:GdVO4 was more suitable for Q-switched mode-locking.
