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. © 1969 The American Institute of Physics.
