Second-harmonic generation of poled BaTiO3 thin films

Second-harmonic generation of 1.064 μm incident light was measured on BaTiO3 thin films prepared by metalorganic chemical vapor deposition. Upon corona poling of the film, the second-harmonic signal was significantly enhanced. The second-order nonlinear optical susceptibility, d, of the poled film r...

Description
Summary:Second-harmonic generation of 1.064 μm incident light was measured on BaTiO3 thin films prepared by metalorganic chemical vapor deposition. Upon corona poling of the film, the second-harmonic signal was significantly enhanced. The second-order nonlinear optical susceptibility, d, of the poled film reaches ∼7.5 times that of the quartz. The enhanced second-harmonic generation shows a very slow decay at room temperature.
