Glow formation and glow-to-arc transition processes of moderate-volume atmospheric-pressure discharge in a CO/sub 2/ laser gas mixture with and without external ultraviolet volume preionization are studied optically by an image-converter-intensifier camera. Three typical types of photographs for (1) glow and arc formation with preionization, (2) glow formation only with preionization, and (3) glow and arc formation without forming network. Discharge development is compared, and dominant factors to suppress arc formation of relevance to designing CO/sub 2/ TEA lasers are discussed.
