The #Pockels effect occurs in specific materials known as electro-optic #crystals. When an electric field is applied to these crystals, their refractive index changes proportionally. This change alters the #polarization state of light passing through the crystal, allowing for precise control over #laser parameters such as intensity and pulse duration.
