Post-compression of picosecond pulses into the few-cycle regime
Prannay Balla, Ammar Bin Wahid, Ivan Sytcevich +18
In this work, we demonstrate post-compression of 1.2 picosecond laser pulses to 13 fs via gas-based multi-pass spectral broadening. Our results yield a single-stage compression fac…

Multi-microjoule GaSe-based mid-infrared optical parametric amplifier with an ultra-broad idler spectrum covering 4.2-16 μm
Kun Liu, Houkun Liang, Lifeng Wang +5
We report a multi-microjoule, ultra-broadband mid-infrared optical parametric amplifier based on a GaSe nonlinear crystal pumped at ~2 μm. The generated idler pulse has a flat spec…
