ABSTRACT
In this work we present a compact two-stage optical parametric amplifier (OPA) pumped at degeneracy by the fundamental of a YbKGW laser system. The output pulses span from 1.7 to 2.5â
µm (120-176 THz) and are compressed to a sub-20 fs duration. This parametric amplifier exploits the broad phase-matching bandwidth at the degeneracy point in bismuth triborate (BiBO) and periodically poled lithium tantalate (PPLT). The result drastically expands the availability of ultrashort pulses with few-microjoule energy from near-infrared (NIR) to even longer wavelengths in the mid-infrared (MIR) spectral region.
