Abstract

A surface initiated plasma temporal attenuator enabling production of CO2 laser pulses with tunable durations (20–90 ns), similar temporal profiles, and near Gaussian spatial profiles, is described. Use of the technique to investigate the pulse length dependence and thereby elucidate the mechanism of CO2 laser damage is demonstrated for uncoated and diamondlike carbon antireflection coated n‐type Ge.
