Polarization of laser beam passing through lithium tantalate crystals

摘要

The given work presents intensity modulation of laser beam with the initial polarization of 45° that passed through the tantalate litium crystal placed between two crossed polarizers depending on the crystal rotation angle and for different crystallographic directions. The obtained modualtion is connected with polarization modulation by means of which the polarization ellipse changes its form in space. Polarization form and position are shown for each direction within the crystal.
