氯化亚汞新型声光器件的优化设计

Optimal Design of Mercuous Chloride New Acoustooptic Devices

氯化亚汞是一种新型的，极具潜力的声光介质。用它作为声光材料设计超声跟踪反常器件，并对其设计参数进行优化，结果表明：此类器件有良好的超声跟踪效果；工艺上易干制作；在保证衍射效率的同时，器件体积比同类ＴｅＯ＿２器件大大缩小。

Mercurous chloride(Hg_2Cl_2)single crystal is a new type of AO medium with good perfor-mance,it is employed to design ultrasonic beam steering birefringent AO device,The optimal design results show that. this kind of device has excellent beam steering effect,and can be easily made in technique,its vol-ume is much smaller than TeO_2 device wtile ensuring its diffraction effidency.
