A calculation is reported of the sensitivity of the intensity of lambda=0.63 ..mu.. radiation, emitted from a helium--neon laser excited by a dc discharge, to discharge current fluctuations. The influence of simultaneous emission of lambda=3.39 ..mu.. radiation (due to a coupled transition) on this sensitivity if found for a wide range of discharge currents and current-fluctuation frequencies. It is shown that fluctuations of the intensity of the lambda=0.63 ..mu.. radiation, resulting from the corresponding fluctuations of the discharge current, can be reduced considerably not only at low (0--1 kHz) fluctuation frequencies but also at a ''resonance'' frequency which amounts to a few tens of kilohertz. The results of these calculations are confirmed by experimental results obtained in the frequency range 0--100 kHz.
