PURPOSE: A laser oscillator is provided to increase the reflective ratio of light by sticking a gold board as only a common pumping reflector composing a laser oscillator. CONSTITUTION: A flash lamp(14) and a YAG(yttrium aluminum garnet) rod(16) are arranged within a common pumping reflector(12). A Q-switched filter(18) is located on a left side of the outside of the common pumping reflector(12) and a partial reflector(22) is located on the right side of the outside. A total reflector(20) is located on a left side of the Q-switched filter(18). A high-voltage generation circuit(10) supplies a high voltage to the flash lamp(14) from the outside of the common pumping reflector(12). The flash lamp(14), when the high voltage is inputted thereto, generates a light energy. The YAG rod(16) absorbs the light energy discharged from the flash lamp(14). The light energy absorbed to the YAG rod(16) is amplified in the YAG rod(16). The partial reflector(22) outputs the partial light delivered from the light energy amplification process to the outside and transmits again the rest to the Q-switched filter(18) through the YAG load(16).
