Abstract:   (3037 Views)
Sliver ion exchanged glasses have been irradiated with focused Ar+ laser beam. Polarized microscope images show birefringent properties for the interaction region. In a pump-probe experiment a He-Ne laser beam has been used to monitor interaction region. It has been observed that the interaction region can couples the spin of a circularly polarized light to orbital angular momentum and change the topological charge of the probing beam after interaction. Interaction region acts as permanent spin to orbital angular momentum coupler depending on the absorbed irradiant energy of the pump laser beam. This is a nonlinear process.
Keywords: Angular momentum, Spin-orbit coupler, Nonlinear process, Topological charge of light.
