Abstract

An experimental investigation of ablative wall flashlamps used to pump high peak power dye laser is presented. The duration of the flashes was about 2 μsec. Three tubes with diameters 1.6 mm, 4.4 mm, and 8 mm were used. We have measured the emission spectrum, the brightness, and the efficiency between 250 nm and 580 nm for electrical energy input densities up to 560 J/cm3. The performance of the flashlamps with xenon and air is shown. The experiments demonstrate that above an energy density of about 150 J/cm3 the gas type and pressure are unimportant but that xenon is always superior.
