A free electron laser (FEL) with wavelength of 450nm and 345nm and YAG laser with wavelength of 532nm were irradiated to surfaces of moderately compressed pure C60 and a mixture of C60 and I2 in vacuum. After laser irradiation the Raman peak of Ag(2)-derived vibration mode of C60 sifted to the lower energy side. By 450nm FEL irradiation the Raman shift of a mixture C60+I2 was as large as ea. 8cm^-1 and was definitely larger than that of pure C60. By 450nm FEL irradiation the decreased in (Ill) lattice spacing of C60 in the mixture sample was by ea. 8 x l0^-3 nm. The obtained results strongly suggest that 3-dimensional polymerization of C60 was effectively induced by laser irradiation and/or addition of iodine.
