Frequently Asked Questions

GuangAo Technology (Wuhan) Co., Ltd is specialized in the field of sound and light technology, particularly in the research, development, production, and sales of acousto-optic devices.

GuangAo Technology was established in 2017.

Acousto-optic devices are used in various cutting-edge fields such as optical fiber sensing, Wiener material processing, quantum technology, and laser velocimetry.

Acousto-optic technology is based on the principle of acoustic-optical interaction, which modulates the frequency, amplitude, angle, and other characteristics of lasers.

An acousto-optic device mainly consists of a piezoelectric transducer, an acousto-optic medium, and a bonding layer.

When an RF signal is loaded onto the piezoelectric transducer, it vibrates to generate ultrasound, which interacts with light in the acousto-optic medium. This interaction forms an ultrasonic volume grating that diffracts incident light, allowing control over its characteristics.

Acousto-optic devices have a high extinction ratio, high damage threshold, high diffraction efficiency, and high response speed.
