基于光纤组束激光的激光干扰技术研究

为了增强激光干扰技术的机动性和灵活性,迫切需要体积小、重量轻的高功率激光干扰源。通过理论分析和数值计算,结果表明,光纤组束激光具有接近80%的组束耦合效率,并可以达到10kW量级的输出功率。以硅材料CCD为例,该功率量级的组束激光可以有效地实施对光电探测器的饱和干扰以及由温升导致的硬损伤。光纤组束激光是一种新型的激光干扰源,在机载光电对抗领域具有广泛的应用前景。

Laser jamming techniq,ue research based,on combined fiber laser

To increase the flexibility of laser jamming technique,the high power laser jamming source of small volume and light weight is urgently needed.Through theoretical analysis and numerical calculation,it has been proved that the coupling efficiency of combined fiber laser is as much as 80%,and the output power could reach 10kW level.Set silicon CCD as an example,the combined laser of such output power could effectively implement the saturation jamming and hard damage induced by temperature rise.Combined fiber laser is a new laser jamming source,which has great application foreground in airborne photoelectric countermeasure field.
