The performance of a 1-J XeCl excimer laser with a variable reflectivity mirror unstable resonator optical cavity is described. The output beam exhibits a flat profile in the near field and a far-field energy distribution with approximately 63% of the energy contained within an angle of 39 µrad (1/e2 spot size).
