Improvement in the conversion efficiency of pulsed optical parametric oscillators using external signal injection

A. G. Marunkov, V. I. Pryalkin, A. I. Kholodnykh


Abstract: An experimental and theoretical investigation was made of the influence of an external dye laser signal on the power and threshold characteristics of a singly resonant optical parametric oscillator utilizing a lithium niobate crystal pumped by the second harmonic of a YAG:Nd laser. When the pulse power of the injected signal was only a few tens of milliwatts, the maximum efficiency of the optical parametric oscillator (OPO) was more than doubled and the unsaturated signal gain reached 10⁶. It was established that the injected signal had a particularly strong influence on the OPO output characteristics at threshold pumping levels.
