Er:YLF-pumped AgGaSe2 optical parametric oscillatorAn AgGaSe2 optical parametric oscillator, pumped by a 1.73-micron Er:YLF laser, has demonstrated reproducible low thresholds, 3.6 mJ, and high-slope efficiencies, 0.31. Threshold and slope efficiency were investigated as a function of resonator length. Spectral bandwidth was measured and correlated with the beam divergence of the pump laser.
