Describe the main features of the Pockels and Kerr electro-optic effects. A linearly polarized Iaser beam passes into an electro-optic medium under the influence of an electric field whose direction is transverse to the direction of propagation. If the polarization direction lies at angle {) to the field, and the field inserts a phase of φ between the polarization component parallel to its direction, compared with the orthogonal component, show that for maximum power transmission through a polarizing analyser placed at the output from the medium, the acceptance direction of the analyser must lie at angle a to the field direction, where:
If ϑ = 30° and ϑ = 65°, what fraction of the original laser power passes through the analyser?
