Carrier-envelope-phase stable, high-contrast, double chirped-pulse-amplification laser system

We present the first carrier-envelope phase stable chirped pulse amplifier (CPA) featuring high temporal contrast for relativistic intensity laser-plasma interactions at 1 kHz repetition rate. The laser is based on a double-CPA architecture including XPW filtering technique and a high-energy grism-based compressor. 8 mJ, 22 fs pulses are produced with 10-11 temporal contrast at -20 ps and a CEP drift of 240 mrad RMS.

Compression of CEP-stable multi-mJ laser pulses down to 4 fs in long hollow fibers

Carrier envelope phase stable 4 fs near-IR pulses with 3 mJ energy were generated by spectral broadening of circularly polarized 8 mJ pulses in a differentially pumped 2 m long composite stretched exible hollow ber. The pulses were characterized using both second-harmonic generation frequency-resolved optical gating (SHG-FROG) and SHG d-scan methods
