Abstract

We have designed and built a chirped-pulse parametric-amplifier system that utilizes a 10 Hz, 300 ps, Nd:YAG pump laser system; a 1.575μm fiber oscillator and amplifier as the signal source; and rubidium titanyl phosphate and potassium titanyl arsenate nonlinear crystals. We obtained 260 fs, 30 mJ pulses centered at 1.550μm, representing a gain of >109 and a peak power of 100 GW. To our knowledge, these are the highest energy and peak power pulses ever produced in the 1.52.0μm region
