Near Diffraction Limited Output from a 100ns XeCl Laser Fitted with a Phase-unifying-cavity

Beam Divergency Studies on a Long Pulse XeCl Excimer Laser

“…The transmission phase difference of the 45 % mirror in the hard edge resonator experiments was nearly IT. This phase difference can be decreased by using a special coating design: the phase unifying mirror [10,11]. Experiments with such a mirror were performed with a resonator with magnification 1.6.…”
