Abstract
A distributed-feedback dye laser having a tuning mirror for reflecting a pumping beam onto an impinging region of a dye cell. A four-link equilateral-parallelogram structure pivotally attached to the mirror is adjustable to translate the tuning mirror along the path of the pumping beam incident on the mirror while simultaneously changing the angular orientation of the mirror. The pumping beam reflected from the tuning mirror is directed toward a predetermined point for all positions of adjustment whereby the beam impinges generally the same region of the dye cell for a wide range of incident angles. The dye cell impinged by the pumping beam may also have a surface, through which the generated laser beam is transmitted, oblique to the laser beam and perpendicular to the dye cell region impinged by the pumping beam.
