Upgrade the Evaluation of the Contribution of the Active Element Cross Section Geometry to the He-Ne Laser Energy Characteristics

Abstract

The models for estimating the contribution of the cross section geometry to the active medium gain of the He-Ne laser have been considered in this work. Expanding the range of studied cross sections it has been found that these models were not analytical and demand the approximate calculations. Modern methods and computing tools should clarify the results of 1960–1970 and it will bring to more accurate results. Some the experimental verification was carried out only in a rectangular cross section. Our model have to complicate taking into account the field intensity distribution in the resonator.
