Laser oscillating apparatus
A laser oscillating apparatus is described comprising: a longitudinally elongated housing defining a hollow interior; a pair of discharge electrodes opposedly disposed in spaced relationship along the longitudinal direction in the interior of the laser's housing to define a lasing region therebetween; a first relatively large planar folding mirror disposed within the interior of the housing at one end thereof and a second relatively large planar folding mirror disposed within the interior of the housing a the opposite end thereof in the longitudinal direction; a relatively small totally reflective concave primary mirror and a relatively small semi-transmissive output mirror each of which is disposed at a predetermined spacing adjacent to the first folding mirror; first independently adjustable support means for holding the first folding mirror, second independently adjustable support means for holding the primary mirror, third independent adjustable support means for holding the output mirror, and forth independently adjustable support means for holding the second folding mirror, each of the independently adjustable support means comprising an L-shaped member which is pivotally mounted at three points with respect to the laser housing; and fixing means operatively associated with each L-shaped member at each pivot point thereof for adjustably mounting the L-shaped member to the housing whereby the relative orientation of the mirror held by the L-shaped member associated therewith may be changed by adjustment of the fixing means.
