The aim of the article is to research physical factors affecting beat frequency and radiation power in He-
Ne tubes of Zeeman lasers in a longitudinal magnetic field. The possibility of increasing beat frequency and
radiation power by optimizing magnetic field and the characteristics of optical resonator are investigated.
The dependence of beat frequency on magnetic field strength showed that once magnetic field strength
exceeds a certain value, difference frequency disappears. Magnetic field is shown to have insignificant effect
on radiation power. The data on the insignificant influence of magnetic field on radiation power are given.
The effect of optical resonator length and mirrors transmission coefficient on beat frequency is studied.
The authors show that beat frequency above 4 MHz can be obtained on short active elements with relatively
high transmittance of output mirror, but at the same time radiation power decreases
Key words: Beat frequency, magnetic field strength, refractive index dispersion
