Abstract
A laser apparatus includes laser, a beam splitter, a phased array acousto-optic deflector (AOD) with one or more transducers, a damper, a galvano deflection unit, and a condensing lens to generate one or more laser beams directed at the electronic circuit. The Galvano deflection unit works with acousto-optic deflector 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.
