摘要
本文介绍了３．８μｍ激光器对新型复合材料４５０１Ａ型玻璃钢进行的烧蚀实验，为了便于对照二氧化碳激光碳化的实验结果，利用微波矢量网络分析仪采用两种测试方法对８．２～１２．４ＧＨｚ微波的传输特性进行了测量，得到了透射率、插入相移等参数。同时也发现，严重的烧蚀损失会降低对微波传输的影响。
it is described about the ablation experiment of a new type composite material named as 4501A heated by 3.8μm laser in this paper. For the convenience of comparising the experiment result with that of CO2 laser damage experiment, relevant parameters of transmissivity, inserted phase shift, etc., have been abtained by measuring 8.2 ￣12.4μm microwave transfer characteristics in 2 ways with a microwave vector net analyzer used. In the mean while, it is observable that the influence of carbonized damage on microwave transfer will be reduced when the ablation is too heavy.
