Internal two-frequency modulation of the intensity of radiation emitted by ruby, neodymium glass, and YAG lasers was achieved by simultaneous excitation of a 5--25 MHz surface acoustic wave on one of the resonator mirrors and longitudinal ultrasonic vibrations of 20--100 kHz frequency of the other mirror. The relationships governing the modulation process were studied as a function of the amplitude and frequency of the acoustic vibrations, parameters of the optical resonator, gain of the active medium, and wavelength of the emitted radiation. Two-frequency modulation of the output intensity produced a new type of lasing kinetics in the form of a regular sequence of pulses with high-frequency internal modulation, and also made it possible to control the intensity, repetition frequency, and time structure of the pulses.
