Annotation: In the paper there are shown the results of investigations of electro-optic (EO) modulators, made of highresistance KTiOPO₄ (KTP), crystals grown in LLC «Crystal T». We measured contrast ratio and axial ratio of the polarization of the laser beam passing through the EO modulator at the maximum and minimum transmission characteristics? and investigates the dependence of the measured coefficients on the direction of polarization of the input optical beam to the modulator.
