СПОСОБ ОПРЕДЕЛЕНИЯ ТУРБУЛЕНТНЫХ ПУЛЬСАЦИЙ ПОПЕРЕЧНОЙ СОСТАВЛЯЮЩЕЙ СКОРОСТИ ПОТОКА АКТИВНОЙ СМЕСИ СО2-ЛАЗЕРА С БЫСТРОЙ АКСИАЛЬНОЙ ПРОКАЧКОЙ ГАЗА

摘要

FIELD: investigating or analyzing materials. ^ SUBSTANCE: method comprises recording and processing the optical signal that carries information on the fluctuation of flow velocity of the active laser fluid of a CO2-laser. The relative fluctuations of the inverse wave are recorded, and d(v2) is determined from the formula proposed. The inverse wave is generated by the internal resonance of four-wave mixing on the nonlinearity of the coefficient of the active fluid of the laser. ^ EFFECT: enhanced accuracy of the measurements. ^ 2 dwg
