Abstract : The patent is directed to a laser in which the output wavelength may be rapidly and continuously varied. The system comprises a dye cell positioned within an optical cavity and a tuning mirror of said optical cavity which is mounted so that it may be rotated. Positioned with respect to the tuning mirror is a diffraction grating such that when the tuning mirror is rotated, the laser beam is scanned across the diffraction grating thereby changing the output wavelength of the laser cell.
