Abstract
A laser system includes two separate active laser-resonators. A first of the laser-resonators delivers laser-radiation at a first wavelength, and the second generates fundamental laser-radiation at second wavelength. The second resonator includes an optically-nonlinear crystal. The radiation delivered by the first laser-resonator is mixed in the optically-nonlinear crystal with the fundamental radiation circulating in the second resonator thereby generating radiation having the sum frequency of the first and second wavelengths. In one example, an OPS-laser-resonator having a fundamental wavelength of 976 nm includes a CLBO crystal. 244 nm radiation from an intracavity-frequency-doubled 488 nm argon-ion laser is mixed in the CLBO with the 976 nm radiation to provide 195 nm radiation.
