We describe a terawatt, femtosecond laser system based on Ti:sapphire amplifiers and the technique of chirped-pulse amplification. The laser output at 807 nm contains 60 mJ of energy in a 125-fs pulse duration. The laser beam is nearly diffraction limited and may be focused to an intensity of 1018 W/cm2 with an f/6 optic.
