Parametric generation of picosecond light pulses in an LiNbO3 crystal at repetition frequencies up to 10 kHz

A study was made of a picosecond resonant optical parametric oscillator employing an LiNbO₃, crystal and synchronously pumped by the second harmonic of the radiation from a quasi-cw YAG:Nd³⁺ laser operating in the regime of active mode locking and Q switching at a repetition frequency up to 10 kHz. The duration of output pulses was 15 psec, the tuning range was 0.85–1.4μ, and the average output power was 25 mW.
