The phase control achievable in a subpicosecond self-mode-locked pulse-compressed Ti:Al[sub 2]O[sub 3] system permits the production of a seed beam for a KrF* (248-nm) system operating near the power limit determined by self-phase modulation in the optical window material used. These limits are [similar to]14 and [similar to]30 GW/cm[sup 2] for CaF[sub 2] and MgF[sub 2] optics, respectively. We show experimental results for CaF[sub 2], which at 248 nm demonstrate a pulse length of [similar to]270 fs, a pulse energy of [similar to]240 mJ, and a resulting brightness of [similar to]2.9[times]10[sup 21] W cm[sup [minus]2] sr[sup [minus]1].
