Abstract
A metallic vapor laser apparatus comprises a discharge tube, a first pulse circuit (200) for generating a first pulse voltage for causing laser oscillation and a second pulse conduit (16) disposed separately from the first pulse circuit and generating a second pulse voltage delayed from the generation of the first pulse voltage by a predetermined time. The metallic vapor laser apparatus is constructed such that, after the first pulse voltage is applied to the discharge tube, the second pulse voltage is applied to the discharge tube and an output voltage of the second pulse circuit (16) is less than an output voltage of the first pulse circuit (200).
