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 cross-polarized wave (XPW) filtering technique and a high-energy grism-based compressor. The 8 mJ, 22 fs pulses feature 10⁻¹¹ temporal contrast at -20 ps and a carrier-envelope-phase drift of 240 mrad root mean square.
我们展示了首个载波包络相位稳定的啁啾脉冲放大器（CPA），其在1 kHz重复频率下具有高时间对比度，适用于相对论强度激光与等离子体相互作用。该激光器基于双CPA架构，包括交叉偏振波（XPW）滤波技术和基于高能光栅的压缩器。8 mJ、22 fs的脉冲在-20 ps时具有10⁻¹¹的时间对比度，载波包络相位均方根漂移为240 mrad。
