We conduct theoretical and experimental research on the internal modulation of the CO_2 laser. The frequency dependence of the amplitude of the varying component of the radiation intensity is shown to have a resonant character. The resonance frequency, the amplitude of the varying component of the intensity, and the width of the resonance curve are determined. Use of the resonant dependence permits attaining a gain in the amplitude of the modulating voltage 60-70 times greater than for external modulation.
