Abstract
Observing the characteristic change in reflectivity of the film surface, we have studied the formation of periodic nanostructure on diamond-like-carbon (DLC) films irradiated by fs laser pulses. In the time-resolved measurement of the reflectivity using the pump-probe technique, a large enhancement of the reflectivity was observed, suggesting a specific phase transition in the fs-laser irradiated film surface.
