Abstract
Aimed at solving the problem of the asymmetry of the output beam of corner-pumped solid-state fundamental-mode lasers, a simple resonant cavity design is presented. Using this method, no optical element needs to be inserted into the cavity. The symmetry of the output beam can be improved effectively by changing cavity parameters. The validity of this method is demonstrated by a corner-pumped Nd:YAG/YAG composite slab Q-switched fundamental-mode laser. The asymmetry of the output beam can be corrected effectively by adjusting the short arm length of the linear cavity and a symmetric output beam is obtained. The resonant cavity design method is simple and practical, which also applies to other lasers with the asymmetric output beam resulting from asymmetric cooling or asymmetric pumping.
