Coherent Synthesizing Technology of Fiber Laser Beams and Applications

光纤激光的相干合成技术是实现高功率高亮度固体激光系统的重要技术途径，它可以在提升光纤激光系统总功率的词时，保持良好的光束质量，从而使输出激光的亮度大幅提高。本文阐述了基于MOPA结构的光纤激光相干合成技术、相位检测控制技术，在此基础上，分析了光纤激光技术在军事中的应用前景，重点研究了在机动平台光电防护系统以及空间攻防系统中的应用。

An important approach to overcome the high output power limitation of a solid laser is to use the coherent synthesizing technology of fiber laser, which would preserve good beam quality while advancing the output power of the fiber laser. In this paper, the coherent fiber laser synthesizing technology based on the Master Oscillator Power-Amplifier and the technology of detecting and controlling of phase state were introduced. Based on this, the applications of fiber laser in the military field were researched with emphasis on mobile platform optic-electronic counter-measure equipments and the space attack-defense Equipments.
