Abstract

A watt-level, single-frequency, continuous-wave (cw) singly resonant optical parametric oscillator (OPO) based on MgO:sPPLT is described. Pumped in the green by a frequency-doubled cw diode-pumped Nd:YVO4 laser at 532nm, the OPO can provide up to 1.59W of single-frequency idler output with a linewidth of 7MHz at pump depletions of as much as 67%. Using a compact ring resonator and optimized focusing in a 30mm crystal, a singly resonant oscillation threshold of 2.84W has been obtained under single-pass pumping. With a single grating period of 7.97μm, continuous signal and idler coverage over 8521417nm is obtained by temperature tuning between 61°C and 236°C. The influence of thermal lensing on idler output power across the SRO tuning range is also verified.
