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%, respectively. Our setup also provides tunable multiband radiation in the 2.03–2.32-µm range and the 2.9–6.2-µm range simultaneously.
