摘　　要：扼要介绍用衍射光脉冲回波技术测量声光介质体波声衰减系数的基本原理、实验装置和样品制备等，并分别测量了声光介质为石英玻璃、声光玻璃和ＬｉＮｂＯ＿３，ＰｂＭｏＯ＿４单晶的体波声衰减系数，给出了实验结果。The bulk aeoustic wave attenuation in acoustooptic media can be measured by using diffraction optic pulse echoing. The paper briefly presents the principle and experimental installa- tion as well as the sample preparation for this measuring method.Several the bulk acoustic wave attenuation coefficients of several acoustooptic media,such as quartz glass,acoustooptic glass,LiNbO_3,PbMoO_4 crystals,are measured,and the results are given.
