Construction and operation of a gas transport CO2 laser |
| |
| Abstract: | The construction and the operation of a CO2 gas transport laser with cylindrical geometry is presented. This work aims at developing a small size and light weight gas transport laser at high output level. This has been accomplished by using 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 1.45 m, diameter 0.54 m 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 28×22 mm3. |
