Abstract
A laser oscillating apparatus has an elongate housing, a pair of discharge electrodes arranged along the longitudinal direction in the interior of the laser housing, and first and second planar folding mirrors arranged at either end in the longitudinal direction of the lasing cavity formed by the discharge electrodes, with the reflecting surfaces of the folding mirror facing the lasing cavity. The folding mirrors are placed with their reflecting surfaces inclined by a predetermined angle with respect to one another. Also in the laser housing are a primary mirror and an output mirror, each of which is arranged with a predetermined spacing in the neighborhood of one of the folding mirrors. At least the primary mirror and the output mirror are arranged so that their attitude is adjustable from the outside of the laser housing.
