✦ Synopsis

LD-pumped actively Q-switched intracavity frequency-doubled Nd:GdVO4=KTP red laser has been introduced. A maximum red average output power of 0:78 W at 671 nm was obtained at pulse-repetition frequency (PRF) of 15 kHz and the optical conversion e ciency was 6.5%. At the incident pump power of 12 W, the shortest laser pulse occurred at PRF of 15 kHz. Its full-width at half-maximum and the highest peak power were measured to be 35:8 ns and 3:38 kW. The largest single pulse energy of 56:3 J was achieved at PRF of 10 kHz. The in uence factors on the Q-switched Nd:GdVO4=KTP red laser have been discussed.
