Abstract
A pulsed tunable laser source of ultraviolet radiation with a linewidth of <400 MHz, a pulse duration of 9 ns, and a pulse repetition rate of 11 kHz pumped by a copper-vapor laser has been developed. Its average output power at a wavelength of 276 nm is 1.5 W. A system intended for laser isotope separation contains a master oscillator based on a dye laser, two amplifying stages with an average output radiation power of 4.5 W at a wavelength of 553 nm, and a radiation-frequency doubler on a BBO crystal. The master-oscillator laser is built according to a scheme with a diffraction grating positioned at an angle close to the glancing angle, a prism beam expander, and an air-filled hermetically sealed Fabry-Perot etalon. The long-term frequency stability of the output radiation is 10 MHz/h.
