A new variant of all-fiber multiple-beam interferometer capable to perform narrow-band filtration of a reflected light, with characteristics similar to those for Fabry-Perot interferometer in a transmission, is presented. The interferometer design accompanied with parameters simulation is conducted, the experimental sample is fabricated and the study of its characteristics is undertaken. Experimental results conform the calculations. This variant of reflection interferometer can be used as one of laser cavity mirrors providing frequency selection of low-powered fiber lasers and laser diodes with short linear cavities. We assume, that this device makes it possible to obtain single-frequency operation with fast continuous tuning of a laser wavelength in a wide spectral range.
本文提出了一种新型全光纤多光束干涉仪，它能够对反射光进行窄带滤波，其特性与法布里 - 珀罗干涉仪在透射时的特性相似。进行了干涉仪设计及参数模拟，制作了实验样品并对其特性进行了研究。实验结果与计算结果相符。这种反射式干涉仪可作为激光腔镜之一，用于低功率光纤激光器和短线性腔激光二极管的频率选择。我们认为，该装置能够在宽光谱范围内实现激光波长的快速连续调谐并获得单频工作。
