Obtain of power retuned radiation in the field of spectrum shorter than 400 nm for the purposes of AVLIS

The second harmonics generation of dye laser in operation on a wavelength of 615 nm was used for the production of the narrow-band radiation with a wavelength of 307.5 nm. Dye laser with two lines of pump copper vapor laser was applied for the generation of the radiation on a wavelength of 615 nm. The summary power of pump radiation of the generator and two cascades of amplification was in the range of 300 W. This makes possible the power of output radiation near 4 W on a wavelength of 615 nm. The range of the line is no more than 300 MHz. The agreement of light pulse-duration, rise of power density of pump radiation in non-linear crystal is called for the increasing output power of radiation on the summary frequency
