Improved performance and rotational spectral characteristics of a doped helical TEA CO2 laser
Abstract
A study has been made of the effect of additives with low ionization potential on the performance of a ballast resistance helical TEA CO2 laser system. It is found that the use of these additives greatly improves the output energy, power, and efficiency of the laser as well as the pressure range of its arc-free operation. In the doped mixture, laser oscillation has been observed on more rotational lines, with the P(20) line being less dominant than in the undoped mixture. The relative energy on the P(20) line is maximum in the pressure range 0.2-1.0 atm. The results are explained using a theoretical model for the multiline TEA CO2 laser.
