Efficient all-solid-state yellow laser source producing 1.2-W average power

Abstract

We report a practical and efficient all-solid-state laser source operating at 578 nm. The source comprises a diode-pumped Nd:YAG laser gain medium producing fundamental output at 1064 nm, an intracavity ${\mathrm{LiIO}}_3$ Raman-active crystal that generates first-Stokes output at 1155 nm, and an intracavity ${\mathrm{LiB}}_3{\mathrm{O}}_5$ frequency-doubling crystal, which frequency doubles the first-Stokes output to 578 nm. $Q$-switched output with as much as 1.2-W average power has been obtained; conversion efficiencies from the fundamental to the yellow as high as 33% have been obtained.
