We have demonstrated a Ti:sapphire/Nd:glass laser system that produces up to 51 J of energy in 395-fs pulses (125TW). Focusing at f/3 to a 2.5-times diffraction-limited spot results in a peak irradiance greater than 1020 W/cm2 . Our 40-cm-diameter gold diffraction gratings have a damage threshold of 0.42 J/cm2 for 320-fs pulses.
