Abstract

All previous pump sources for continuous-wave optical parametric oscillators (cw OPOs) have been confined to the spectral region 488 - 532 nm. We report what we believe to be the first UV-pumped cw OPO. Pumped at 364 nm by a single-frequency argon-ion laser and using LBO as the nonlinear crystal, we demonstrate a threshold of 115 mW, and temperature tuning from 502 - 494 nm (signal) and 1.32 - 1.38 μm (idler).
