The results show : laser beam far field intensity distribution deflect to the wave length increasing direction , the influence to laser beam far field intensity distribution of different inflow mach number is little than the influence of different inflow pressure ; flow field has more aberration to 1 . 315um laser beam than to 10 . 6um laser beam
研究表明激光束远场强度分布都向流场光程增大的方向偏折，喷流出口马赫数的变化对激光束远场强度分布的影响较小，喷流出口压力的变化对激光束远场强度分布的影响较强；在相同的流场结构下，流场对波长1 . 315 m激光束的干扰要明显强于对波长10 . 6 m激光束的干扰。
