System and method for altering the optical properties of a material

Abstract

A system for changing the configuration of a transparent, resilient material, for the purpose of altering its optical properties, requires obtaining a topology for the material. The obtained data is then used to create a computer program for operating a laser unit. In accordance with the program, the laser unit creates incisions within a defined operational volume, inside the material, to weaken the material (i.e. change its internal stress distributions). Specifically, the incisions are made on predetermined surfaces (e.g. cylindrical surfaces) in the operational volume by Laser Induced Optical Breakdown (LIOB). As a consequence of the incisions, the material undergoes the desired configurational change in response to external forces applied on the material.
