Abstract
In this work ، a CW CO2 laser system was constructed and operated. This system employs an intermediate heat sink unit in order to increase cooling rate of the active medium, which is CO2:N2: He mixture. The obtained results in this work explain that using the heat sink unit causes the output laser power to increase to 52W compared to 5W obtained from the same system without using the heat sink unit. This heat sink technique can be considered as reasonable solution to increase cooling rate of the active medium throughout forming an intermediate region in which the gas flow rate is high.
