A Reliable Flashlamp Pumped Tunable Organic Dye Laser

Abstract
An improved flashlamp pumped dye laser is described. Reliable long term operation has been attained by using a low inductance capacitor bank. A linewidth of 0.3 Å and a beam divergence of 2.5×10−3 rad result from more uniform optical pumping in the flashlamp. Tuning ranges of several organic dyes are presented.
