Selection of resonator of high power and high brightness solid state laser

The dynamic stable regions of several kind of resonator, which can be used in high power laser, have been analyzed. Two kind of solid state laser resonator reported recently have been evaluated, and problems in those resonator have been pointed out. The best design for high power and high brightness solid state laser has been put forward: the best resonator is composed of a short radius concave mirror and a convex mirror.
