Abstract

The existence of two sources of the photionization in UV preionized sealed CO2‐N2‐He‐(CO) lasers has been established. One is steadily created in the laser gas mixture by the electrical discharge and is identified as NO and NO2. The second source is associated with an impurity in any CO gas used as part of the initial gas mixture.
