Influence of Flow Velocity on the Output Power of High Pressure CW CO2 Lasers

Abstract

This article studies the overall effects of flow speed and pressure on CO2 laser device characteristics within a range of even greater flow speeds and high pressure taking the occasion to investigate the potential displayed by high pressure instruments. Considering the lens length to be 5 cm and the lens height to be 3 cm, under conditions of relatively high pressure, we select the light cavity or chamber position to be 0.5-5.5cm. Primary consideration is placed on positions where output light powers are relatively high, lying close to the upper reaches of the gas flow. Besides this, under the low pressures, the range of permissible degrees of output power coupling is relatively large.
