Apparatus of Ultrasonic Grating for Lasers and Photonics Physics Lab

The Apparatus of Ultrasonic Grating for Lasers and Photonics Physics Lab is designed to demonstrate the acousto-optic effect, where ultrasonic waves create periodic variations in the refractive index of a medium, forming an ultrasonic grating. When light passes through this modulated medium, diffraction occurs, producing patterns that can be analyzed to study the interaction between sound and light.This apparatus provides a practical method for measuring the speed of sound in a liquid medium through optical diffraction techniques. The system enables students to investigate fundamental principles of acousto-optics while developing essential laboratory skills in optical alignment, measurement, and data analysis.
All components are mounted on a precision optical rail, allowing convenient setup and accurate alignment. The apparatus is suitable for undergraduate and advanced physics laboratories, offering reliable results and valuable insight into modern optical technologies.
