Paper Abstract

In this paper, we review some recent advances in optical parametric oscillator (OPO) technology, discuss major coherent source issues and then propose possible solutions that have relevance to remote chemical sensing. The authors discuss their latest result on two OPO schemes. 1) Energies up to 1.2 mJ/pulse and continuously tunable OPO output from 6.7 to 9.8 micrometers was obtained using a 5 X 5 X 25 mm3 type II AgGaS2 crystal, pumped a second OPO using NCPM ZnGeP2 to generate output near 8 micrometers . The tandem OPO produced pulse energies of > 1.5 mJ at 7.8 micrometers with an energy conversion efficiency of 6.8 percent. Finally, we describe schemes for generating multiple photons in the 8-12 micrometers band from one initial 1 micrometers pump photon, and thereby increase the quantum efficiency when OPOs are pumped by Nd:YAG lasers.
