Abstract
The performance of different super-Gaussian unstable resonators applied to a high-gain, short-pulse XeCl laser has been investigated. The output beam divergence measurements show that in the XeCl laser the output arises from an initial burst of spontaneous emission which is amplified as it propagates within the unstable resonator and after each round trip an output pulse with different spatial characteristics is obtained.
