Intense Mid-IR pulses with controlled waveforms are an important tool to extend the ponderomotive cut-off in strong field experiments. Especially in high-harmonic generation this can be used towards the generation of water-window harmonics [1]. To co

375-W 37.5-μJ less than 170 fs laser system utilizing nonlinear pulse compression in fused silica

Publikováno v: SPIE Proceedings.

We present a novel, robust and efficient scheme for nonlinear pulse compression at highest average powers, which is based on self-phase modulation in a bulk nonlinear medium placed inside a multi-pass-cell (MPC). The scheme is suitable for the compre

Nonlinear pulse compression in a multi-pass cell

Autor: Jan Schulte, Johannes Weitenberg, Andreas Vernaleken, Thomas Sartorius, Peter Russbueldt

We demonstrate a scheme for nonlinear pulse compression at high average powers based on self-phase modulation in a multi-pass cell using fused silica as the nonlinear medium. The scheme is suitable for compression of pulses with peak powers exceeding

The Innoslab amplifier comprises a diode-laser partially end-pumped thin slab crystal and a folded single-pass optical amplification path. While this configuration differs in many respects from other slab amplifiers, it shares characteristics with pa
