Experimental Study of Gas Kinetics of a Fast-Axial Flow Kilowatt CO2 Laser
Abstract
The paper describes the rapid flow of a gas mixture in a fast-axial flow kilowatt level CO2 laser. A high-flow-velocity wind tunnel is introduced. Gas pressure, gas flow velocity, and its method of measurement are analyzed. A wind tunnel was constructed and gas experiments were conducted. The gas flow velocity was as high as the speed of sound. Experimental data are given. Worldwide, it is accepted that the kilowatt level, fast axial flow CO2 lasers are an ideal light source, with high efficiency and good quality of light beam for high-power laser industrial processing. Within the range of 1 and 3kW abroad, these lasers have replaced most lateral-direction flow and slow-speed axial-flow devices. In China, the study of these devices is just beginning with this experiment. The article presents the results of experimental studies of gasdynamics of a kilowatt-level, fast-axial-flow CO2 laser.
