Beam divergence studies on a hard edge unstable resonators for a long pulse XeCl excimer laser [PDF]
, 1997 The focusability of a long pulse XeCl excimer laser has been improved using confocal positive branch unstable resonators where the outcoupling is done through the convex mirror. A nearly diffraction limited output beam is obtained from hard edge unstable
