Abstract

An analysis of the polarization dynamics of the light modulated by means of the KDP type crystals is performed in terms of the Stokes parameters of the modulated light. Both the shape of the modulated signal and its spectral structure are presented. The linear and nonlinear ranges of the modulator operation are studied both theoretically and experimentally. Some particular cases of practical interest are presented..
