A study of the specific power output of a gasdynamic CO2 laser with wedge-shaped and profiled nozzles
Abstract
Measurements of the specific output of a continuous-wave gasdynamic CO2 laser are reported for four different nozzles used alternatively. It is shown that nozzles with a profiled supersonic section provide a specific power output of 17 J/g, compared with 13 J/g for wedge-shaped nozzles. The use of a well-known simplified process for the manufacture of nozzle blading (radius contour) is shown to reduce the specific power output to about 9 J/g. Large-scale single nozzles are recommended for use in industrial laser devices.
