Nonlinear Phase Shifts by Cascaded Optical Rectification and Linear Electro-Optic Effect

Abstract

Cascaded optical rectification and the consequent linear electro-optic effect have been investigated theoretically. Nonlinear phase shift of the fundamental beam caused by the cascading process was found to be proportional to the input intensity and the propagation length as in the Kerr effect. It is notable that the depletion of the fundamental optical pulse energy is negligible even for large nonlinear phase shifts.
