Abstract

We employed a 9-mm long periodically-poled KTiOPO4 (PPKTP) crystal with a domain inversion period of 37.8 μm in an optical parametric oscillator (OPO) to generate sub-nanosecond pulses around 2.8 μm. With a 1-cm long OPO cavity in a singly resonant configuration with double pass pumping the OPO threshold was 110 μJ at 1064 nm (1-ns pump pulses at 1064 nm). The maximum idler output energy reached 110 μJ (quantum conversion efficiency of 32.5%). The signal pulse duration (FWHM) was 0.72 ns and the estimated idler pulse duration was 0.76 ns. At room temperature the signal and idler wavelengths were at 1722 and 2786 nm.
