Paper Abstract

Microspike-arrays were fabricated by irradiating a femtosecond laser on a tungsten surface through a mask opening in air. Natural logarithm of the calculated intensity distributions diffracted at the edge of the mask opening was qualitatively consistent with the experimental results of the shape and arrays of microspikes fabricated. The shape and the array of microspikes depend on the intensity distribution diffracted at the edge of the mask opening. This microspike-array has a potential to be micro emitter tips.
