ABSTRACT:
An optically pumped laser system having a configuration capable of efficiently coupling pumping radiation with a gain medium to provide an outlet beam having a wavelength in the ultraviolet and visible spectrum is disclosed. A gain medium including halide, rare and noble gas elements is contained within a cell at total pressures from four to thirty atmospheres. The gain medium is ionized by a spark source within the cell and interacted with optical pumping radiation to provide a diffuse electrical discharge. An optical resonator having the discharge disposed therein efficiently extracts energy from the gain medium to provide an output beam having a wavelength in the visible spectrum when the total pressure of the gain medium is high, typically greater than nine atmospheres and a wavelength in the ultraviolet spectrum when the pressure is moderate, typically less than five atmospheres.
