High-average-power, mid-infrared, widely tunable, picosecond optical parametric oscillator based on OP-GaAs
High-average-power, mid-infrared, widely tunable, picosecond optical parametric oscillator based on OP-GaAs
This paper reports a high-average-power mid-infrared source based on an orientation-patterned gallium arsenide (OP-GaAs) optical parametric oscillator (OPO) with wide wavelength tunability. An average power of 4.8 W of signal (3093 nm) and 3.5 W of idler (5598 nm) was achieved at a pump power of 25.5 W. Tuning ranges of 2895 nm-3342 nm (signal) and 4935 nm-6389 nm (idler) were obtained. The idler-resonant OPO offered good beam quality of the mid-infrared idler waves with an M2 of 1.1. High-average-power induced thermal effects for the OP-GaAs OPO were observed.

Abstract
This paper reports a high-average-power mid-infrared source based on an orientation-patterned gallium arsenide (OP-GaAs) optical parametric oscillator (OPO) with wide wavelength tunability. An average power of 4.8 W of signal (3093 nm) and 3.5 W of idler (5598 nm) was achieved at a pump power of 25.5 W. Tuning ranges of 2895 nm-3342 nm (signal) and 4935 nm-6389 nm (idler) were obtained. The idler-resonant OPO offered good beam quality of the mid-infrared idler waves with an M2 of 1.1. High-average-power induced thermal effects for the OP-GaAs OPO were observed.
