We report a full experimental comparison study on the injection of a Ti:Sa multi-TW amplifier chain with a standard 15 fs Ti:Sa oscillator and a 35 fs frequency doubled fiber oscillator. The study highlights that the Ti:Sa oscillator with high performances in term of pulse duration and spectral width can be replaced by the frequency doubled fiber oscillator to seed Ti:Sa amplifier chains without almost any compromise on the output pulse duration and the picosecond contrast. Finally, we demonstrate for the first time of our knowledge a 30 TW and 33 fs Ti:Sa amplifier injected by a fiber oscillator.
