- Instrument Introduction
The principle of the crystal transverse electro-optic effect: the modulation of laser amplitude caused by changes in the crystal’s refractive index induced by an electric field is known as the electro-optic effect. By utilizing the typical LiNbO₃ crystal, students will master the principles and experimental methods of crystal electro-optic modulation. Students will learn to measure the crystal’s half-wave voltage and electro-optic constant using a simple experimental setup. Observe changes in the crystal’s optical properties caused by the electro-optic effect and the interference phenomena of collimated polarized light. Conduct a demonstration experiment on laser communication.
