Abstract
This paper reports the experimental results demonstrating that the nanostructured surface of diamondlike carbon film can be shaped so as to have a sawlike pattern with obliquely incident ppolarized femtosecond laser pulses. The nanoscale surface shape was observed as functions of incident angle, superimposed number and fluence of laser pulses and characterized with height and slope angle of the inclined surface. This results show that the inclined shape is formed with the non-uniform spatial distribution of local field enhanced on the nanostructured surface.
