Paper Abstract

Neodymium-doped strontium fluoro-vanadate is a favorable laser material for diode-pumped, compact, and passively Q-switched lasers. We have constructed a high power passively Q-switched Nd:S-VAP laser with a fiber coupled 10 W laser diode pumping. To avoid severe thermal deposition and thermal induced crystal fracture, several measures have been taken in the laser design. With a Cr4+:YAG of initial transmission of 80%, stable laser pulses of duration of 3 ns, energy of 45 micro-joule and repetition rate of 23 kHz are obtained at an incident pump power of 7.75 W.
