Paper Abstract

The pulse parameters of a Cu-HyBrID laser were measured in a large range of discharge conditions. It was shown that the laser efficiency is determined by an adequate pre-pulse electron density. Almost constant laser average power and efficiency can be obtained in very different pulse repetition rates provided other discharge parameters were adjusted in order to maintain the optimal pre-pulse electron density. We observed that the pulse width depends mainly on the HBr concentration while the pulse energy is mainly dependent on the absolute HBr pressure and repetition rate.
