Longitudinal Pockels cell (a) Sketch schematically the structure of a longitudinal Pockels cell in which the applied field is along the direction of light propagation, both parallel to the z-axis (optic axis). Suggest schemes that would allow light to enter the crystal along the applied field direction. (b) Suppose that an LiNbO3 crystal is used. LiNbO3 is uniaxial and n1 = n2 = no (polarizations parallel to x and y) and n3 = ne (polarization parallel to z). Neglecting the rotation of the axes (same principal axes in the presence of an applied field), the new ordinary refractive index is

Neglecting the rotation of the axes (same principal axes in the presence of an applied field), the new ordinary refractive index is Calculate the half-wave voltage required to induce a retardation of p between the emerging and incident waves if the free-space wavelength is 1om. What are their polarizations? (Note: For LiNbO3 at 633 nm,
