Abstract
Abstract A single mirror serves both as the output mirror for the pumping gas laser and the high reflectance mirror for the dye laser. THe mirror is formed on one surface of a lens having a low dispersion characteristic. The dye cell is positioned at the focus of the lens on the opposite side of the lens from the common mirror. The output of the dye laser is taken through a second mirror formed on an output lens of high dispersion material. Tuning is done by moving the output lens toward and away from the dye cell, or by varying the tilt of an etalon plate positioned between the dye cell and the output lens, or both.
