Effect of gas decomposition in multi-joule TE/TEA CO2 lasers excited by magnetic-spiker sustainer technique

Y. X. Tang, R. G. Harrison

Research output: Contribution to journalArticlepeer-review


Investigation of the effect of dissociation products on the discharge stability and laser performance of TE/TEA CO2 lasers using magnetic-spiker sustainer excitation technology is presented. The tolerance of the discharge to O2/CO concentration is determined, giving improved results to that found in conventional systems. Both solid state and gaseous catalyst are also investigated for extending operational lifetime of the laser gas mixture.
