  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.
