  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 producing 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 CEP
noise.
