Longwave-IR Optical Parametric Oscillator in Orientation-Patterned GaAs Pumped by a 2 micron Tm,Ho:YLF Laser (Preprint)

Abstract

We demonstrate longwave infrared (LWIR) generation with an optical parametric oscillator (OPO) based on quasi-phasematched orientation-patterned gallium arsenide (OPGaAs). The OPGaAs OPO was directly pumped with a Q-switched lambda=2.054 micron Tm,Ho:YLF laser. OPGaAs samples representing three different grating periods were used to explore the LWIR OPO performance yielding outputs ranging from lambda=2.5-2.7 micron (signal) and lambda=8.8-11.5 micron (idler). Slope efficiencies for the combined signal and idler outputs reach as high as 26% while slope efficiencies for only the idler reached 8%. Spectral measurements of OPO output confirm good agreement with theoretical calculations.
