Laser device

A method for creating patterns using a laser system, comprising:

• providing a computer system comprising software for reading input files containing a pattern design and controlling the direction and intensity of a laser beam;
• directing the laser beam onto a material according to the pattern design using a phase-array acousto-optic deflector (AOD) formed by grinding an optical element to form two or more steps each with a predetermined height, depositing a conductive layer over one or more steps at different heights, and adhesively attaching one or more transducers on the one or more steps with an epoxy layer, wherein one side of each transducer electrode is coupled to an input and the other side of the transducer is coupled to ground through the conductive layer and wherein the optical element comprises a slanted end, wherein the slanted end comprises a compound angle to move reflected sound field out of a laser beam working range, wherein the slanted end forms a 30 degree angle measured from a long side of the optical element to a short side of the optical element, and wherein a surface of the slanted end comprises a 2 degree slope;
• and
• applying one or more finishing touches to the material.
