Paper Abstract

The nonlinear optical properties of ethyl red (ER) doped PMMA film are measured, and the effective indexes of refraction n2 of the film at the three wavelengths are -1.08×10-9, -2.28×10-9 and -1.35×10-10m2W-1 respectively. It indicates that ER sample has a larger optical nonlinearity compared with other optical materials. The nonlinear absorption of ER film at the three wavelengths is measured respectively. The self-diffraction of the film at 441.6nm and at 535nm is investigated respectively, and the results indicate it possesses high quality of optical limiting. The lasers of 441.6nm and 535nm can all induce thermal self-defocusing effects in the film.
