WebOct 30, 2024 · Measurements of optical Kerr gate confirm that the nature of such optical nonlinearity arises from a pure electronic process, since it occurs in a time scale shorter than the pulse duration (130 fs). 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 ...

WebMar 21, 2012 · For optical Kerr gate measurements the two-beam setup is slightly modified. The energy in one of the paths is reduced to ∼6 μJ so that this beam path acts as a probe beam and the other beam path acts as a pump beam. In the probe beam path a λ /2 plate is placed before the sample and an analyzer is located after the sample (Fig. 1 (d)).
