The repetition rate is user-controllable between ~100MHz and ~1GHz, without adjusting the OPO cavity length.

Abstract

We demonstrate a picosecond singly resonant optical parametric oscillator (OPO), which is synchronously pumped by a source consisting of a gain-switched laser diode and a chain of Yb-doped fibre amplifiers. The OPO produces up to 7.3W at 1.54µm (signal) and 3.1W at 3.4µm (idler) from 24W of average pump power. Pulse durations are typically ~17ps. M2- values of 1.1 × 1.2 (signal) and 1.6 × 3.2 (idler) are measured at high output power. Signal and idler tunability is demonstrated from 1.4µm to 1.7µm and 2.9µm to 4.4µm, respectively, by accessing different gratings of the MgO-doped periodically poled LiNbO3 (MgO:PPLN) crystal. The repetition rate is user-controllable between ~100MHz and ~1GHz, without adjusting the OPO cavity length.
