High-mode-volume high-energy (70 mJ) high-brightness (1.6 x 1014 W cm-2 Sr-1) laser beams have been extracted from a high gain short-pulse XeCl laser with a super-Gaussian unstable resonator. These results are obtained by increasing the cavity magnification factor to 6.6 and the output mirror peak reflectivity to 78%. The output beam divergence is seen to decrease from an initial value of ~0.2 mrad down to nearly diffraction limited after 6 ns for the short gain build-up time of the active medium. © 1993 IEEE
