Construction and operation of a gas transport CO2 laser
Abstract
The construction and operation of a CO2 gas transport laser with cylindrical geometry is presented. This work aims at small size and light weight gas transport laser at high output level. This has been accomplished by a single metallic cylinder for electric discharge, recirculation and the cooling of the gas mixture. More than 1kW laser power was obtained from a laser of the length of 1.45m, diameter 0.54m and cca weight 180 kg. Typical parameters were: pressure 40 Torr, CO2:N2:He = 1:8:11, discharge current 8 A, efficiency 12%, and laser spot 28 x 22mm sq.
