Enhancement of nonlinear optical properties of composite material based on Al2O3 by iron

We fabricate the Fe:Al2O3 composite material by using the ion implantation technique. The implantation was performed at energy of 35 KeV with ion concentration of . The supercontinuum spectrum was measured to show the nonlinear refractive property of this kind of sample. The Kerr-lens autocorrelation method was used to measure the nonlinear optical refractive index of this Fe:Al2O3 composite material for the first time. The measuring result was at a wavelength of 800 nm. The nonlinear optical refraction of Al2O3 can be dramatically enhanced by Fe ion implantation. The XPS spectrum was measured to analyze the valence state of Fe in the surface of this composite material.
