A AgGaSe2 Optical Parametric Oscillator Pumped by a Raman-Shifted YAG laser
Abstract
The operation of a AgGaSe2, infrared parametric oscillator pumped by a Raman-shifted YAG laser at 1.9 micrometers is reported. Output energies up to 1.2 mJ were measured near 4.5 micrometers with a photon conversion efficiency of 10%. Phase matching is possible to produce outputs over the 2.3- to 12.0- micrometer region. Fluence thresholds as low as 0.031 J/sq cm were measured using an 8-ns pump pulse. The thresholds were shown to be cavity-length dependent in agreement with theory. No optical damage was observed at fluences up to 0.18 J/sq cm at the 1.9 micrometers pump wavelength.
