摘要

Operation of an optical parametric oscillator based on CdSiP_(2) and pumped at 1064 nm is demonstrated at a repetition rate of 1 kHz. The maximum output idler energy of 24 (mu)J at 6.125 (mu)m corresponds to an average power of 24 mW. Increasing the crystal temperature up to 150 deg in the noncritical (90 deg) configuration leads to idler wavelength tuning from 6.117 to 6.554 (mu)m. Subnanosecond pulse durations are obtained for the signal and idler as a result of the 1 ns pulse duration of the pump, made possible by the rather short crystal and cavity lengths (approx1 cm).
