摘要

摘要所提议的光纤装置是一个在共同包层中的锥形纤芯阵列。讨论了该装置在多元素激光系统中用于辐射求和的可能性。为获得光学上独立的通道，明确了器件参数的形成标准，这使得在远区产生窄辐射光束成为可能。推导出了远区辐射场的分析表达式，以及获得接近衍射发散的设备参数。这种装置可以无限增加发射器的数量，从而提高窄光束的辐射功率。

Analysis of a Device Based on a Multicore Fiber with Tapering Cores for Radiation Summation in Multichannel Laser Systems

The proposed fiber-optic device is an array of tapering cores in a common cladding. Possible applications of the device for radiation summation in multielement laser systems are discussed. The criterion is specified for the formation of the device parameters to obtain optically independent channels, which makes it possible to produce a narrow radiation beam in the far zone. Analytical expressions are derived for the radiation field in the far zone and the parameters of the device for obtaining a close-to-diffraction divergence. This device allows an unlimited increase in the number of emitters to increase the radiation power in a narrow beam.
