Gradient index have been made by a laser polymerization in a copolymer thin films containing barium ion using the irradiation of scanning YAG laser. The monomer of copolymer is compound acrylic acid, organic carboxylic acid containing barium ion (45 mol%) and chlorostyrene. The laser polymerized gradient index thin films (thickness: 10μm) showed a 700μm wide, gaussian shape in the gradient-index distribution, whose maximum refractive-index difference is 0.024, and length is 1 cm.
