A Ti:sapphire multipass amplifier with high efficiency at the repitation of 1 kHz is described. The incident 0.66 W pulses are amplified to 7.2 W when the pump power is 23 W. The energy extraction efficiency is about 30%. After compressed in the compressor, we obtained 4.5mJ, 38fs pulses with peak power greater than 0.1 TW.
