多通道声光调制器的研制

Development of the Multichannel Acousto-optic Modulator

介绍了多通道声光调制器的基本工作原理。设计并制作了中心频率为 80 MHz,带宽为 10MHz的 LN/ ZF- 6四通道线性声光调制器 ,对这类器件的制作工艺进行了分析和研究。实验测得器件的指标为 :中心频率 75MHz,衍射效率大于 10 % (1.5W输入功率 ) ,带宽 15MHz,已经达到实用要求。

A brief review of the fundamental acousto optic interaction theory is given. The considerations of design and fabrication for multichannel Bragg cell are studied. A four channel LN/ZF 6 modulator with 75 MHz center frequency, 15 MHz bandwidth and more than 10% diffraction efficiency has been designed and fabricated.
