Photoassisted Poling Induced Second Harmonic Generation with Inplane Anisotropy in Azobenzene Containing Polymer Films.
Abstract
Photoassisted poling of azobenzene containing polymer films at room temperature using polarized Ar(+) laser beam as pump light was studied. Irradiating the films with p-polarized pump light at an incident angle to the normal during the poling process, second harmonic generation with in-plane anisotropy could be induced. Second order nonlinear optical coefficient, d33, of the poled sample was measured to be 20 pm/V. The second harmonic generation properties induced by photoassisted poling and thermal assisted poling were compared.
