Abstract
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.
