Abstract
An optical resonator for a laser oscillating apparatus has an arrangement of folding mirrors facing one another across the lasing gas medium that radiates the laser beam. The arrangement includes a pair of reflecting surfaces that are approximately orthogonal to one another and effectively face the lasing gas medium as a whole. Also, the laser beam that is incident from the lasing gas medium is caused to be reflected successively from both reflecting surfaces to be emitted in the direction of the lasing gas medium.
