Abstract
A tunable laser system emitting coherent radiation selectively variable over the range of wavelengths from about 2760 A to about 3220 A utilizes a crystal, composed of fluoride of at least a Column IIIb metal doped with trivalent ions of cerium and pumped with high average power pulses. The crystal is emplaced in an optical cavity having means such as diffraction grating, etalon, or optically-tunable prism, to vary the coherent emission wavelength.
