Abstract: The development of a Ti:sapphire CPA laser facility named SILEX-I with the peak power of hundred terawatt level is reported. SILEX-I includes the femtosecond oscillator, the Offner stretcher, the regenerative amplifier, the pre-amplifier, the main amplifier, the power amplifier, the vacuum compressor and the vacuum target chamber. SILEX-I has three output powers: 5 TW, 30 TW, and hundreds terawatt, and there are corresponding target chamber for different physical experiments. The peak power of 286 TW and the pulse width of 29.8 fs after the compressor are obtained. The focal intensity is 3.36×1020 W/cm2 with the focal spot of 5.7 μm.
