FIBER-OPTICAL ACTIVE OSCILLATOR

摘要

FIELD: transducers for measuring temperature, pressure, acceleration. SUBSTANCE: device has fiber-optical laser, which light guide mates collimator which generates parallel light source towards reflecting surface of cavity. Output end of light guide together with reflecting surface of cavity provides two-mirror optical cavity of fiber-optical laser. Reflecting surface of cavity is located at angle with respect to axis of light beam. Self-oscillating mode in system of fiber-optical laser and cavity is achieved due to modulation of amplitude of reflection index of optical cavity of fiber-optical laser due to light induced angular deviations of one of mirrors. Reflecting surface of cavity is used for this task. EFFECT: increased stability of measurements. 2 dwg
