The main players in China's acoustic-optic deflector market include Fujian Crystal Technology, Antelaser, CETC, and Qingjin Optoelectronics, among others.

Acoustic-optic deflectors, abbreviated as AOD or AODF, are optical devices that use the acousto-optic effect to control and deflect the direction of laser beams. They offer advantages such as good stability, fast response speed, small size, lightweight, low power consumption, and high resolution. They are widely applied in various fields, including optical communication, beam scanning, spectroscopy, material processing, non-destructive measurement, and semiconductor inspection. The types of acoustic-optic deflectors are diverse, including surface-wave acoustic-optic deflectors, lithium niobate acoustic-optic deflectors, and silicon acoustic-optic deflectors.

An acoustic-optic deflector typically consists of two main components: an electro-acoustic transducer and an acousto-optic medium. The electro-acoustic transducer, made from piezoelectric ceramics, converts electrical signals into ultrasonic signals. The acousto-optic medium mainly includes materials such as lithium niobate crystals, lithium tellurite crystals, and glass, which all exhibit acousto-optic activity.

Acoustic-optic deflectors belong to the category of optoelectronic devices. In recent years, the Chinese government has attached great importance to the development of the optoelectronic device industry and has introduced various incentive policies, including the "Guiding Opinions on Promoting the Development of Energy Electronics Industry" and the "Notice on Issuing the Action Plan for Steady Growth in the Electronic Information Manufacturing Industry from 2023 to 2024." With future national policy support, the development speed of China's acoustic-optic deflector industry will further accelerate.

According to the "2024-2029 Acoustic-optic Deflector (AOD/AODF) Industry Market In-depth Research and Investment Prospect Prediction Analysis Report" published by the Sinothink Industry Research Institute, acoustic-optic deflectors are primarily used in fields such as optical communication, beam scanning, spectroscopy, material processing, non-destructive measurement, and semiconductor inspection. In optical communication, acoustic-optic deflectors can be used for analyzing, modulating, and controlling optical signals. In beam scanning, they are employed in MEMS scanning mirrors and confocal microscopes. In material processing, they are utilized in laser micromachining systems, enabling micro-drilling of HTCC green ceramics. With further research, the application scope of acoustic-optic deflectors is expected to expand even further.

The global acoustic-optic deflector market is dominated by players such as BRIMROSE Corporation (USA), Intra Action Corporation (USA), and AA OPTO-ELECTRONIC (France). Compared to developed countries overseas, China's acoustic-optic deflector industry started later but has shown rapid development momentum, with local enterprises now possessing the production capacity for high-end products. The main players in China's acoustic-optic deflector market include Fujian Crystal Technology, Antelaser, CETC, and Qingjin Optoelectronics. Fujian Crystal Technology, as a representative enterprise in China's acoustic-optic deflector industry, has the capability to independently research, develop, and produce products such as high-speed acoustic-optic deflectors and large-aperture air-cooled acoustic-optic modulators.

Industry analysts at Sinothink believe that as an optoelectronic device, acoustic-optic deflectors are widely used in various fields. With future growth in market demand, the prosperity of China's acoustic-optic deflector industry will further improve. In the early stages of industry development, due to factors such as high technical barriers, China relied heavily on imports for acoustic-optic deflectors. However, in recent years, benefiting from national policy support and the continuous efforts of local enterprises, the market share of high-end acoustic-optic deflectors in China has continued to increase.
