The operation of a continuous-wave mode-locked silver gallium selenide (AgGaSe2) optical parametric oscillator is reported. The OPO was synchronously pumped by 40 ps long pulses of the 1.55 µm-signal radiation from a noncritically phase-matched KTP- OPO operating at a repetition rate of 75.4 MHz. The tuning range extended from 1.94 µm to 2.56 µm and from 3.95 µm to 7.75 µm for the signal and idler wave, respectively. A total average output power of up to 520 mW was generated.
