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 µm. The 28.5-µm grating PPKTP crystal provides SRO tuning over 1.14–1.27 µm (signal) and 2.23–2.73 µm (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 µm and 2.29–2.57 µm, 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 µm.
