Abstract

Using noncritically phase-matched 1cm2-aperture KTiOAsO4 (KTA) crystals in an optical parametric oscillator (OPO), we have demonstrated a sustained average signal power of 33  W at 1534.7  nm. To our knowledge, this is the highest-average-power signal ever generated by an OPO. The pump source was a 100-Hz Q-switched 1064-nm Nd:YAG laser. Compared with that of the similar and more-common material KTiOPO4, idler absorption in KTA is negligible, allowing high-power operation with minimal thermally induced refractive distortion in the OPO crystal.
