Short delay time UV preionized TEA CO2 laser operating with binary CO2/H2 and CO2/He gas mixtures
Abstract
In order to obtain short tail-free output laser pulses from a TEA CO2 laser, parametric study of the laser operation with CO2/H2 and CO2/He binary gas mixtures containing high CO2 concentrations was carried out. A small scale UV preionized short delay time TEA CO2 laser was employed. In terms of the maximum extractable output pulse energy and power, the more conventional CO2/He gas mixture was found to be inferior in comparison with the CO2/H2 mixture proposed here.
