Optimum for the Gasdynamic System in a Fast-Axial-Flow CO2 Laser

Abstract

It is reported that the temperature rise of the discharge mixture, in a fast-axial-flow CO2 laser, can be decreased by increasing both the mass flow rate and the speed of the mixture through the laser tube. However, increasing the mixture speed, in a practical gas dynamic system, will lead to decreasing the mass flow rate, and thus the discharge tube with appropriate cross section, which matches the properties of the given blower driving the mixture to flow, should be chosen to obtain the optimal operation of the laser.
