Effect of gas mixture on the output characteristics of a CW CO2 laser

Abstract EN

In this work, the effect of partial amounts of gases in gas mixture of a CW CO2 laser on the output power was investigated.

Also their effect on the condition determining the glow-discharge self-sustaining required for pumping the active medium was studied.

Two fit relations were derived to predict the output laser power and the electric field to unit pressure ratio as functions to the partial amounts of gases.

Results presented in this work could be used fruitfully to determine some of the optimum operational conditions of glow-discharge low-power CW CO2 lasers.
