Abstract : An attempt has been made to fill in some of the development since December 1962 and to add in formation pertinent to the high-power gas laser problem. A summary of currently known gas laser transitions is given. Summaries of available absolute and relative transition probabilities and other pertinent data are also presented in tabular form. The main effort has gone into the evaluation of existing systems from the point of maximum saturated output power and towards under standing the limitation on the power output and efficiency. It is generally to be expected that the highest output systems will fall at the short wavelength end of the spectrum-although severe complicati these systems may arise from competition by higher gain long-wavelength tran sitions from the same upper state. It is con cluded that the known inelastic collision cross sections for ionizing collisions between pairs of excited atoms are sufficient to rule out gas flow systems of the type considered by Penner.
