Abstract
We report on an agile nonlinear device able to generate 300W, mJ-level, transform-limited pulses from few picoseconds down to few tens of femtoseconds. The system is based on an industrial-grade 330W laser, delivering 400fs pulses followed by an efficient, >90% throughput, gas-filled multipass cell where self-phase modulation occurs. Adjustment of the chamber gas pressure and incoming pulse chirped either favors spectral compression or nonlinear compression, leading to the generation 300W, 1mJ, high beam quality and nearly transform-limited pulses of 2ps down to 30fs within a single system. This source is a versatile tool for both industrial and scientific applications.
