摘要

目前,自主激光系统的广泛应用要求减少其组成中的激光源所消耗的供应能量,同时提高其输出能量特性。本工作的目的是实际验证基于环形延迟线的系统中激光束合并的可能性。建立了在环形光纤延迟线上实现同步激光束组合方案原理的实验装置。给出了该装置的原理图,详细介绍了其工作原理,并对其组成进行了分析。值得注意的是,为了实现从该装置的光电探测器接收到的电信号的客观测量,并进行了由分离器去除并在该装置的光纤路径中形成的部分激光辐射功率的测量。测量结果以光电探测器的电信号和分路器输出的功率值的波形表示。给出了输出功率和循环功率随初始激光束功率的变化曲线。分析结果表明,激光束合并发生在环形光纤延迟线内。此外,还发现该方案使初始光束的功率提高了1.05 ~ 1.11倍。

Research of Laser Beam Combining in Ring Fiber-Optic Delay Line
At present time widespread use of autonomous laser systems supposes reducing of supply energy, consumed by laser sources that are included in their composition and at the same time increasing of their output energy characteristics. The objective of this work was practical confirmation of possibility of laser beam combining in systems based on a ring delay line.The experimental setup that implements the principle of synchronous laser beam combining scheme on the ring fiber-optic delay line, developed by authors earlier, is made. The schematic diagram of the manufactured setup is presented, its operation principle is described in detail and its composition is considered. It is noted that in order to achieve the objective measurements of electrical signals received from the photodetector of the setup and measurements of the part of laser radiation power removed by the splitter and formed in the fiber-optic path of the setup are performed. Results of measurements are presented as the waveforms of electrical signals from the photodetector and of power values at the output of the splitter. Plots of dependence of the output power and the circulation power on the power of the initial laser beam introduced into the setup are presented.Analysis of results showed that the laser beam combining occurs in the ring fiber-optic delay line. Besides, it was found that the proposed scheme provides an increase in the power of the initial beam by 1.05…1.11 times.
