Abstract

We report a high-repetition-rate picosecond optical parametric oscillator (OPO) based on CdSiP2 (CSP) that is synchronously pumped by an Yb-fiber laser at 1064 nm and provides high average power in the deep-infrared (deep-IR) at 79.5 MHz. The OPO is tunable across 6205–6710 nm in the idler, providing as much as 105 mW of average power at 6205 nm and >55  mW over nearly the entire tuning range. The deep-IR idler output exhibits passive power stability better than 2.3% rms over 12 h in good beam quality. The near-IR signal pulses from the OPO have a Gaussian pulse duration of 19  ps, measured at 1284 nm. We have investigated the temperature tuning characteristics of the OPO and compared the data with the theoretical calculations using the most recent Sellmeier equations and thermo-optic coefficients for the crystal. To the best of our knowledge, this is the first picosecond OPO based on CSP operating at MHz repetition rates.
