-Instrument Introduction

The principle of transverse electro-optic effect in crystals, which modulates the amplitude of laser light and changes the refractive index of the crystal caused by the electric field, is called electro-optic effect. By utilizing typical LiNbO3, the principle and experimental methods of crystal electro-optic modulation can be mastered. Learn to measure the half wave voltage and electro-optic constant of crystals using simple experimental devices. Observe the changes in crystal optical properties caused by the electro-optic effect and the interference phenomenon of converging polarized light. Conduct laser communication demonstration experiments.
