SIMULATION OF PS LASER PULSES INDUCED ABSORPTION PHENOMENA IN MATERIALS

Abstract

The laser-induced damage in transparent or non-transparent materials represents an important active field of research as part of laser/material interactions studies. Most of research activities within this field are aiming to laser micro-processing of transparent optical materials, glasses, ceramics and metals. An example of such laser micro-processing techniques is drilling micro channels through a glass plate and drilling transverse holes through single mode optical fibre cladding and core. The latter example of research activity has an important purpose consisting of designing and manufacturing micro-nanoscale optical fibre sensors with improved capabilities. An important issue to be underlined refers to the necessity to develop simulation procedures based on accurate theoretical models of these physical processes in order to use a precise computer control of micro-processing technology.
