High-repetition-rate and short-pulse-width electro-optical cavity-dumped YVO4/Nd:GdVO4 laser.

ABSTRACT

In this paper, an electro-optical cavity-dumped 1.06 µm laser using YVO4/NdGdVO4 composite crystal under 808 nm diode-laser pumping was reported. Theoretical calculations showed that the temperature distribution in YVO4/NdGdVO4 crystal was lower than that in GdVO4/NdGdVO4 and NdGdVO4 crystals under the same conditions. A constant 3.8±0.3 ns pulse width was obtained and the repetition rate could reach up to 50 kHz with a maximum average output power of 5.6 W and slope efficiency of 40.7%, corresponding to a peak power of 31.1 kW.
