title: Picosecond mid-infrared optical parametric amplifier based on the wide-bandgap GaS(0.4)Se(0.6) pumped by a Nd:YAG laser system at 1064 nm.
abstract: Operation of a GaS(0.4)Se(0.6) optical parametric amplifier is demonstrated with a 5-11 μm idler tuning range, maximum energies of ∼10 μJ for sub-30-ps pulse durations, and performance ∼3 times better than with pure GaSe.
