Times to learn the Pockels Cells
By applying electric field control to the electro-optic crystal, the refractive index of the electro-optic crystal in a certain direction can be changed, so that the Pockel unit of the electro-optic modulator can be used as a variable half wave plate to change the polarization state. The wave Kerr unit of the electro-optic modulator is placed between two vertical polarizers to realize light intensity modulation. Electro optic effect can be divided into transverse electro-optic effect and longitudinal electro-optic effect. In the transverse electro-optic effect, the propagation direction of light is perpendicular to the electric field, while in the longitudinal electro-optic effect, the propagation direction of light is parallel to the electric field. Crylink's Pockels battery uses a protective window with high-quality AR coating to ensure high transmission rate and prolong the service life of the equipment. The half wave voltage of longitudinal electro-optic effect is independ...
