Abstract

A continuous-wave singly-resonant optical parametric oscillator (SRO) has been implemented using a 20 mm long crystal of periodically poled KTiOPO4 (PPKTP) intracavity-pumped at room temperature within a Ti:sapphire laser. The device delivers a maximum output power of 455 mW at a non-resonant idler wavelength of 2.47 mu m. The 28.5-mu m grating PPKTP crystal provides SRO tuning over 1.14-1.27 mu m (signal) and 2.23-2.73 mu m (idler) limited by optical coating bandwidths and corresponding to a pump tuning range of 805.5-811.2 nm. Temperature tuning of the device generated signal and idler ranges of 1.18-1.26 mu m and 2.29-2.57 mu m, respectively, corresponding to an average tuning rate of 1.2 nm/degree (signal) and 4.5 nm/degree (idler). Ring-cavity configuration of the device resulted in generation of 115 mW of single-frequency idler output at 2.35 mu m. (C) 2000 Optical Society of America.
