Abstract :
A long-pulse ultraviolet (UV) laser source has been demonstrated. It was obtained by the harmonic generator of a flashlamp-pumped alexandrite laser operating in the normal-pulse mode. We obtained tunable UV light in the wavelength region 365-390 nm. A 375-nm output generated 90 mJ. The pulsewidth was 240 μs. The UV-laser output was successfully transmitted through a 3-m-long step-index-type silica fiber with a core diameter of 600 μm
