Title

A comparative study on surface modifications induced in a dielectric material and a metal using femtosecond laser

Abstract

"Damage caused by ultrashort laser intense light pulses generated in Femtosecond regime in metals and dielectrics at high fluence values limits the performance of these high power short laser pulses. The geometrical parameters, such as diameter, depth, etc., and the morphologies of the ablated areas are strongly influenced by the number of pulses, pulse duration and the spatial beam profile of the laser. In this work, major theoretical models of ablation mechanism in metals [3, 8] and dielectrics [9, 10], physics behind formation of ripples [11] are discussed...and the experimental details of machining parameters are presented"--Introduction, leaf 7.
