Abstract

The performance of a 0.45 J KrF excimer laser with an unstable cavity using a phase-unifying mirror as an output coupler is described. The output beam having a cross section of 2.4×1.2 cm2exhibits a smooth far field profile with 86.5% of the total near field energy contained within a far-field full angle θ≤0.05 mrad. The measurements for determining the beam quality factor M2and the beam angular stability are also reported. © 1997 American Institute of Physics.
