Abstract

Volume holographic gratings and two-dimension periodic microstructures in azodye-doped polymethylmethacrylate were fabricated, respectively, by interference of two coherent beams of a femtosecond laser and by interference of three coherent beams of a nanosecond laser. The volume holographic gratings consist of two parts, surface relief gratings on both surfaces and refractive index modulated volume gratings in the interior of the polymers. The diffraction efficiency ofthe first-order Bragg for the gratings was estimated to be 91%. In the experiments for interference ofthree beams, the period of two-dimension periodic microstructures was changed by adjustment of the angle between the three writing beams. Experimental results showed that two-dimension periodic microstructures with O.69-µm period were formed on the surface ofpolymer samples.
