Output energy parameters of a KULON-10Cu-UV laser

The output energy parameters of an industrial KULON copper vapour laser equipped with a nonlinear frequency converter based on DKDP and BBO crystals are studied. The average and peak powers, as well as the energies and pulse durations of radiation at wavelengths of 510, 578, 255, 271, and 289 nm, are measured in the regime of high-speed pulse modulation, which is used in lasers of this series. The maximum average power was 420 mW at a wavelength of 271 nm (DKDP) and 350 and 110 mW at 255 and 289 nm, respectively (BBO). It is experimentally shown that the average energy characteristics of UV radiation can be controlled on-line by changing the pulse repetition rate of the laser.
