Abstract
The phase control achievable in a subpicosecond self-mode-locked pulse-compressed Ti:A1203 system permits the production of a seed beam for a KrF∗ (248-nm) system operating near the power limit determined by selfphase modulation in the optical window material used. These limits are ∼14 and ∼30 GW/cm2 for CaF2 and MgF2 optics, respectively. We show experimental results for CaF2, which at 248 nm demonstrate a pulse length of ∼270 fs, a pulse energy of ∼240 mJ, and a resulting brightness of ∼2.9 × 1021 W cm-2 sr-1. © 1993 Optical Society of America.
