Abstract
A laser system for creating patterns on clothing includes a laser source; a phased array acousto-optic deflector (AOD) configured to control the direction and intensity of the laser beam; a computer comprising software for reading input files containing pattern designs and controlling the AOD to direct the laser beam according to the pattern designs; a fabric preparation station for washing and preparing fabric before laser treatment; a post-laser wash station for removing debris from the fabric after laser treatment; and a clothing finishing station for applying finishing touches to the fabric. The AOD includes an optical element having a surface with one or more steps formed thereon; a conductive layer formed on the surface with the steps; one or more crystals secured to each step; and electrodes positioned on each surface of each crystal.
