Dependences of Output Powers on the Discharge Current in Single-Line and Two-Line Oscillations of He-Ne Lasers

Abstract

A general method of expressing the output powers of gaseous lasers on a single line or simultaneous oscillations on two lines as a function of pumping rates and transition probabilities is developed from the standpoint of an electronic network analog of the rate equations. By application of this method to the 1.15 µ, 6328 Å, and 3.39 µ lines of He-Ne lasers, the dependences of their powers on the discharge current are discussed and found to be in agreement with experimental results. Furthermore, example of simultaneous oscillations of the 1.15 µ and 6328 Å lines as well as those of the 6328 Å and 3.39 µ lines are treated, giving results which are also in agreement with experimental results. Features of the dependences of the output powers on the discharge current in the simultaneous oscillations are stated in connection with those in the single-line oscillations.
