High-efficiency multiply pulsed copper vapor laser utilizing copper chloride as a lasant

Abstract

A copper vapor laser operating at a wavelength of 5106 Å and a pulse repetition rate up to 30 000 pulses/sec has been constructed and investigated. The best results obtained to date are as follows: energy and power density of 35 μJ cm−3 and 1.7 kW cm−3; pulsewidth 20 nsec; average density 0.7 W cm−3; laser efficiency 1%.
