Abstract
We present a CEO-stable 1.1 kW CPA system that is designed to drive a few-cycle-generation stage (<6fs pulse duration) and a subsequent atto-second beamline at the ELI-ALPS facility in Szeged. It currently delivers >300W of average power at 100kHz repetition-rate providing <10fs pulses. The chirped-pulse-amplification system (CPA) demonstrates excellent noise properties with <220mrad of the integrated carrier-envelope-offset (CEO) noise (10Hz to 20MHz) at a pulse repetition rate of 80MHz while the relative-intensity-noise (RIN) stayed <0.3%. This is the first CEO-stable laser system at 1kW level average power.
