The model of radiation of the damped nonrelativistic oscillator is the basic one for the description of many phenomena discussed in electrodynamics, radiophysics and quantum optics. However, in standard textbooks, the topic is presented briefly. Sometimes important details for practical calculations are omitted. In this paper, we derive exact formulas for spectral angular distribution of the damped oscillator radiation. The approximate expressions for oscillator with low attenuation coefficient have been obtained. Attention is paid to the physical interpretation of the formulas obtained.
Модель излучения затухающего нерелятивистского осциллятора является базовой для описания многих явлений, рассматриваемых в электродинамике, радиофизике, квантовой оптике. В статье последовательно выведены точные формулы спектрально-углового распределения излучения затухающего осциллятора, получены приближенные выражения для осциллятора с малым коэффициентом затухания. Обращено внимание на физическую интерпретацию полученных формул.
