This paper reports a study of He-Ne/I₂¹²⁷ lasers that have a narrow spectral line and output radiation with no frequency deviation. As a result, the monochromaticity of the radiation is improved, and the radiation line is 30 kHz wide. The instability of the laser's radiation is investigated. The Allan variations of the frequency are shown for various stabilized lasers.
