Abstract
There is disclosed an apparatus for translating the focal points of curved mirrors in a dye laser along a straight line comprising an experimentally selected pivot point for each mirror and a means for causing each mirror to pivot about its pivot point. Rotation of the mirror about the pivot point causes the incoming beam to strike the mirror in a different place on the curved surface such that the angle of reflection changes in such a manner as to compensate for the arcuate movement of the mirror around the pivot point. Also disclosed are hinge designs to allow a mirror to pivot about an apparent pivot point which is much farther away from the mirror than the hinge. Also disclosed are a method for attaching the mirror supports to the laser frame in dye laser construction and a method for tuning the dye laser so constructed for optimum lasing efficiency.
