【 摘 要 】

The paper shows analytically that any resonant interaction of quantum particles in media having no symmetry centre with a high-frequency exciting field produces low-frequency radiation. Media particles may not necessarily have a constant dipole moment. Conditions are identified when carrier frequency of low-frequency radiation coincides with nutational oscillations of resonant level populations and is readily controlled both by high-frequency resonant radiation intensity and by resonance detuning.
