Nonlinear pulse compression of 515  nm pulses toward 20  fs and its application in all-solid-state high-harmonic...

To capture the dynamics of light-matter interaction, intense ultrafast pulses are required. In this study, we present an all-solid-state nonlinear pulse compression setup that successfully compresses the second harmonic of 1030 nm, centered at 515 nm, from 189±19fs to 25±3fs, using self-phase modulation in a few pieces of fused silica plates. The M² measurements show near-perfect beam quality with MX2 and MY2 being 1.16 and 1.17, respectively. We performed all-solid-state high-harmonic-generation measurements following this configuration. This work demonstrates industrial-graded all-solid-state high-harmonic generation in the extreme ultraviolet regime.
