Second harmonic generation in isotropic chiral medium with nonlocality of nonlinear optical response by
Optics Express
|April 7, 2017
Abstract:
The second harmonic generation in the bulk of an isotropic chiral liquid with spatial or temporal nonlocality of its quadratic response is studied analytically. The fundamental pulsed beam has Gaussian time envelope and carries a polarization singularity at its axis. The influence of the topological charge and the handedness of the polarization singularity on the polarization state of the signal beam is revealed.
