高衍射效率声光调制器的设计与实现
Design and Implementation of Acousto-Optic Modulator with High Diffraction Efficiency
摘要
Abstract
This paper introduces an acousto-optic modulator(AOM)featuring high diffraction efficiency and a large aperture.The AOM is designed for operation at 1 064 nm,with an effective aperture of 10 mm and a center operating frequency of 80 MHz.Low-absorption quartz was selected as the acousto-optic medium,while high-efficiency lithium niobate served as the piezoelectric transducer.Through optimized design and bonding processes,combined with a heat-conductive and electrically conductive heat dissipation solution utilizing a pressure block and adhesive pad,a diffraction efficiency of 98.4％was achieved.This AOM simultaneously exhibits excellent outstanding beam quality and high beam pointing stability.The research provides a critical high-performance optical component for high-power laser applications.关键词
