摘要

Recently the dynamics of the resonant ablation of polymers and toluene employing mid-infrared femtosecond laser (fs laser) has been calculated by using the fluid equations. The advantages and shortcomings of the mid-infrared fs laser resonant ablation have been discussed. The results indicated that the mid-infrared fs laser is a powerful tool for removing a polymer coating on the substrate made of another polymer due to good wavelength selectivity. In this paper we studied the resonant ablation processes of polymer coatings with ultrahigh molecular weight. The influence of the initial temperature was discussed and the selection rules of laser parameters were given. We also discussed how to make hollow patterns in a polymer film, and the results demonstrated the acceleration of the ablation process caused by suspending the film.
