Abstract

A simple technique has been developed that increases the power output of a conventional flashlamp pumped dye laser by typically one order of magnitude and, for some dyes, much more. This is achieved by igniting a low-energy prepulse discharge through the flashlamp just prior to firing the main flashlamp discharge.
