ABSTRACT:
The invention relates to a flash lamp pumped neodymium laser incorporating a fluorescent converter material which significantly improves the pumping efficiency of the neodymium laser. The fluorescent converter material is aluminum tungstate doped with trivalent chromium ions. The doped material combines broad absorption bands, short fluorescence decay times, and high quantum efficiency and emission in the region which is efficiently absorbed by neodymium.
