title: Toward an optical synthesizer: a single-frequency parametric oscillator using periodically poled LiNbO(3).
abstract: We demonstrate single-frequency operation of a cw quasi-phase-matched singly resonant optical parametric oscillator (SRO). We obtained widely tunable output from 1.66 to 1.99 mum (signal) and from 2.29 to 2.96 mum (idler) by employing a periodically poled lithium niobate multigrating chip. Using a single-frequency miniature Nd:YAG ring laser as a pump source results in SRO output with high spectral purity and frequency stability(<10 MHz/min), which can be continuously tuned over 2 GHz without mode hops. We obtain a minimum SRO threshold of 260mW by resonating the pump wave in the SRO cavity.
