WebOptical Kerr Gate. The optical-field-induced birefringence can change the polarization of a beam propating in the medium. Conversely, measurements of the change of the beam polarization should allow us to deduce values of the induced birefringence. The optical Kerr effect, which usually refers to the phenomenon of linear birefringence induced ...
