Generating energetic, few-cycle laser pulses with stabilized carrier-envelope phase at a high-repetition rate constitutes a first step to access the ultra-fast dynamics underlying the interaction of matter with intense, ultrashort pulses in attosecond science or high-field physics. We present here a Ti:Sa-based 1 kHz TW-class laser delivering 17.8 fs pulses with 350 mrad shot-to-shot CEP noise based on an original 10 kHz front-end design. In parallel to this short pulse duration operation mode, it is possible to tune the output wavelength of the front end within a 90 nm range around 800 nm.
