硼酸盐晶体中的声光衍射
Acoustooptic Diffraction in Borate Crystals
摘要：
实验研究了a-BaB_2 O_4和Li_2B_4O_7晶体的声光衍射效率。晶体显示出相当好的AO材料。当电信号功率为P=0.7W时，a-BaB_2 O_4晶体的声光衍射效率为h=30%，当电信号功率为P=0.56W时，纵波衍射效率为h = 15%。对于Li_2B_4O_7，在P= 0.81W的纵向声波下，相同参数达到h=21%。
英文摘要：
The efficiency of acoustooptic (AO) diffraction in a-BaB2O4 and Li2B4O7 crystals is studied experimentally. The crystals are shown to be quite good AO materials. The efficiency of AO diffraction in a-BaB2O4 reaches h=30% at the electric signal power of P=0.7W for the transverse acoustic wave and 15% at the power of P=0.56W for the longitudinal wave. The same parameter for Li2B4O7 reaches h=21% at P=0,81W for the longitudinal acoustic wave.
