| 中文摘要 | the refractive indices of crystalline phase-change films are usually obtained by thermal-induced crystallization. however, this is not accurate, because the crystallization of phase-change film in rewritable optical disks is laser induced. in this study, we use the initializer to crystallize the phase-change films. the dependence of the refractive index n and the extinction coefficient k of the phase-change films on the initialization conditions are studied. remarkable changes of the refractive indices (especially k) are found when the initialization laser power density is 6.63 mw/mum(2) and the initialization velocity is 4.0 m/s. at the same time, the structure changes of the phase-change films are also studied. this dependence is explained by the structure change of the films. these results are significant in improving the accuracy of optical design and the thermal simulation of phase-change optical disks, as well as in the study of phase-change optical disks at shorter wavelengths.
