Abstract

Advances in the development of crystals with good nonlinear properties have made optical parametric oscillators (OPOs) strong candidates for generation of coherent radiation. These technological advancements have renewed research in the development of solid state 8 - 12 micrometers coherent OPO LIDAR sources for remote chemical sensing applications, if millijoule pulse energies are adequate and short (ns) pulses are beneficial. We present recent advances in OPO technology that have generated tunable, 3 - 5 micrometers and 8 - 12 micrometers radiation. Specific pump source technologies to be addressed are CO₂, Nd:YAG, Er and Ho:host materials. The paper will examine nonlinear materials such as ZnGeP₂, AgGaSe₂, AgGaS₂, and CdSe and their relevant parameters.
