Transmission Through a LiNb0 3 Plate
Examine the transmission of an unpolarized He-Ne laser beam (λo= 633 nm) normally incident on a LiNb0 3 plate (ne = 2.29, no = 2.20) of thickness 1 cm, cut such that its optic axis makes an angle 45° with the normal to the plate.
a) Determine the lateral shift at the output of the plate and the retardation between the ordinary and extraordinary beams.
b) Sketch the beams
