Abstract

It is shown that the stepwise excitation process from the Cd(II) ground state is the dominant one for the upper state of the 441.6 nm laser line in the positive column Ne-Cd+ laser discharge. The much smaller laser output power in Ne-Cd than that in He-Cd cannot be explained by the nonexistence of the Penning excitation process for the laser upper state in Ne-Cd. It is explained by the smaller stepwise excitation rate for the laser upper state in Ne-Cd than that in He-Cd and the influence of both the laser lower state density and the loss of the cavity.
