Shock-wave termination of laser action in coaxial flash lamp dye lasers

Abstract

Shock‐wave‐induced optical distortion of dye laser solutions in conventional coaxial flash lamps has been observed. An inwardly propagating radial shock wave is generated in the solution upon flash lamp discharge, causing virtually complete scattering of axially directed light within a few microseconds. Laser action is prematurely terminated since rapidly induced optical distortion becomes a substantial impediment during the period of effective laser pumping.
