连续波光参量振荡器定向红外干扰

介绍了基于光纤激光器泵浦的光学参量振荡器发展现状及其在定向红外干扰技术中的应用前景，对定向红外干扰技术的一些基本原理进行了讨论。利用自研的一台基于光纤激光器泵浦的连续波光学参量振荡器，通过周期调谐的方式分别实现3.414,3.630和3.820 μm的瓦级中红外激光输出。采用这3个波长的激光对中红外热像仪进行了干扰原理性实验。对比实验结果可以得出:对于3.820 μm波长的中红外激光，当其辐照的HgCdTe探测器前功率密度大于10 W/cm2量级时，在传输750 m距离后，热像仪实现饱和效果并且非饱和区域图像灰度级发生较大变化，达到了掩盖有用信号的目的。

Abstract

The development of the fiber laser-pumped optical parametric oscillator and its application in the directional infrared countermeasures technology was described. Some basic theories of laser infrared countermeasures were discussed. Based on the self-developed fiber laser-pumped continuous-wave optical parametric oscillator, 3.41, 3.63 and 3.82 μm infrared lasers in the watt-level output were achieved by way of periodic tuning. The infrared jamming experiment was carried out by using all the three wavelengths of the laser and a mid-wave infrared thermography. Through comparison of the experimental results for the 3.82 μm output laser in the transmission 750 m distance, it is obtained that the gray level of the infrared thermography saturated and unsaturated zone results changes greatly when the radiation density before the HgCdTe detectors is greater than 10 W/cm2. It can achieve the purpose of covering useful signal, and can make the guidance system failure.
