Abstract :
A tunable mid-infrared optical parametric oscillator has been demonstrated using a noncritically phase matched AgGaSe2 crystal with pump wavelength tuning. Average power experiments have generated several hundred milliwatts of 2.63 and 3.71 μm radiation using a high-repetition-rate, multiwatt 1.54 μm pump source. Interferometric measurements of the AgGaSe2 crystal during operation indicated only minor thermal lensing
