Abstract: | We describe a cw optical parametric oscillator (OPO) with multigrating periodically poled LiTaO(3) . Pumped by a single-frequency 532-nm laser, the OPO emits single-frequency radiation at wavelengths from 0.77 to 1.73mum with as much as 60 mW of output power. Mode-hop-free operation for as long as 50 min, a low frequency drift (<70MHz/h), and as much as 700-MHz continuous frequency tuning of signal and idler are demonstrated. |
