Abstract
We demonstrate a high-efficiency ZnGeP2 optical parametric oscillator (OPO) pumped by another KTP OPO in a multimode-pumped tandem OPO configuration. The maximum optical-to-optical and slope efficiencies were 32% and 42.5%, r espectively. Our setup also provides tunable multiband radiation in the 2.0 3-2.32-mu m range and the 2.9-6.2-mu m range simultaneously.
