Abstract

Summary form only given. Nd:YVO/sub 4/ offers highly efficiency miniature or microchip lasers due to its high absorption and emission cross-sections. However, its poor thermo-mechanical properties prevent high power laser operation. Much effort has gone into laser material research to find a high absorption coefficient laser medium with high thermal shock parameters. Lately, a high optical quality Nd:YAG laser material of polycrystalline ceramic has been reported. In the paper, we have demonstrated a highly efficient oscillation in a Nd:YAG ceramic microchip laser.
