Abstract
A high powered solid-state laser apparatus that is small in size and low in cost. The solid-state laser apparatus includes a semiconductor laser, a laser crystal, an etalon element, a non-linear wavelength converting element, and an output mirror, which are used to reduce the number of the fundamental wave length mode pieces, thereby raising an efficiency of the Q-switch. Thus, an output power of the laser is increased.
