Abstract

Fabrication of scattering media by femtosecond laser pulse irradiation in Poly(methyl methacrylate) (PMMA) material is presented. Focused femtosecond laser pulse can fabricate void with a few μm in PMMA material. Random distribution of voids can work as a scattering medium. We measure the scattering properties of fabricated void structure by changing the void density. By comparing the experimental results and numerical results, we discuss the possibility of control of scattering coefficient by void density.
