Method of generating tunable coherent ultraviolet light at wavelengths below 2500 A

摘要

A method for obtaining efficient production of short- wavelength, continuously-tunable ultraviolet light by parametric mixing of optical frequency radiation in a nonlinear crystal. The method involves mixing the second harmonic of a tunable, visible-wavelength laser, an organic dye laser, for example, with the fixed-wavelength output of a near- infrared laser, e.g., a Nd:YAG laser, in a conventional nonlinear crystalline material such as ADP or KDP.
