Abstract

The present invention concerns a chirped pulse amplification system comprising an oscillator (1) generating ultrashort seed pulses (10); a stretcher (3) generating temporally stretched pulses (20); an optical amplification system (4) generating stretched amplified pulses (30); a compressor (5) suitable for generating high energy ultrashort pulses (40) and a CEP feedback loop comprising measurement means suitable for measuring pulse to pulse carrierenvelope phase drift of the high energy ultrashort pulses (40) and carrierenvelope phase drift correction means. According to the invention, the CEP feedback loop comprises an analog CEP drift detection system placed at the output of said chirped pulse amplification system and analog CEP drift correction means comprising a CEP modulator placed in the beam path of said chirped pulse amplification system.
