Abstract : This patent discloses a method and system for extraction of visible optical energy from gas lasers having simultaneous ultraviolet and visible transitions. In this disclosed method, stimulated emission on the UV transition of rare-gas halide molecules is converted to a wavelength which coincides with the wavelength of the visible transition using a dye laser cell mounted in a common optical cavity with the visible laser. Excitation of the rare-gas halide laser produces high gain UV and low gain visible transitions. The UV is focused into a visible dye cell, and simulated emission occurs in the dye cell which is contained in an optical cavity also containing the gas laser. The stimulated emission of the dye cell is amplified by the discharge-pamped gas laser medium. Since the gain of the dye laser is very high, the arrangement allows laser emission at the visible wavelength to build-up very rapidly during the gas laser excitation discharge pulse. Laser emission has been produced over a waveguide bandwidth between 460 and 510 nm. (Author)
