Abstract

A 32.1 W laser-diode-stack pumped acoustic-optic Q-switched Nd:YVO ₄ slab laser with hybrid resonator at 1064 nm was demonstrated with the pumping power of 112 W and repetition rate of 40 kHz, the pulse duration was 32.47 ns. The slope efficiency and optical-to-optical efficiency were 37 and 28.7%, respectively. At the repetition rate of 20 kHz and pumping power of 90 W, the average output power and pulse duration were 20.4 W and 20.43 ns, respectively. With the pumping power of 112 W, the beam quality M² factors in CW operation were measured to be 1.3 in stable direction and 1.6 in unstable direction.
