Recent developments of high brightness solid state slab-geometry lasers are reviewed. Firstly the definitions of a brightness and a parameter of focusability: Q are described. Secondary, methods to realize the high brightness solid-state lasers are summarized. These methods are classified intothe three categories: (1) reduction of thermal distortion, (2) the compensation of thermal distortionand (3) a resonator for high beam quality. In these methods, a zigzag slab geometry laser withan unstable-stable hybrid-resonator is a promising candidate for a high bright-ness solid state laser. Finally, a list of the performances of high power slab geometry solid-state lasers is presented.
