Original Ti:Sa 10 kHz front-end design delivering 17 fs, 170 mrad CEP stabilized pulses up to 5 W

Abstract

We present a compact 10 kHz Ti:Sa front end relying on an original double-crystal regenerative amplifier design. This new configuration optimizes the thermal heat load management, allowing the production of a 110 nm large spectrum and maintaining a good beam profile quality. The front end delivers up to 5 W after compression, 17 fs pulses with a 170 mrad shot-to-shot residual carrier-envelope phase noise.
