Experimental investigation on coherent beam combination of a three-element fiber array based on target-in-the-loop technique

摘要: 实验验证了一种利用目标回光在远场实现相干合成的技术—目标在回路技术.建立了目标在回路相干合成的物理模型,利用可同时调整光程和光束倾斜的自适应光纤光源准直器,同时补偿合成光光束间的平移和倾斜相差,实现了基干目标在回路的三路光纤传输激光间相干合成,获得了接近理想情况的合成效果,文章为在实际大气环境中实现多路相干组束的长距离传输提供了参考.

Abstract: A kind of target-in-the-loop（TIL） technique which promises the coherent combination of multi-element laser beams in far field is experimentally demonstrated.The physical model of coherent beam combination（CBC） based on TIL is established.A kind of adaptive fiber optics collimator correcting piston and tip/tilt errors simultaneously is employed to compensate phase errors between beamlets.The CBC of a 3-element fiber array based on TIL is successfully achieved and a perfect effect of CBC is captured.In this paper,we present a reference for long-distance transmission of multi-element coherent beams in real atmospheric environment.
