<p>A laser-marking system that emits a laser beam (30) through an acousto-optic deflector (39) and onto a product (10) to form dot-markings on the product. The acousto-optic deflector defects the laser beam depending on the frequency emitted to the acousto-optic deflector. A controller (22) controls the laser to emit a laser beam when desired, and controls a digital frequency synthesizer (34) to emit the desired frequency to the acousto-optic deflector. The user (43) and/or controller may configure the laser-marking system to determine the efficiency of the acousto-optic deflector and to determine correct amplitudes of dot frequencies to give the desired dot intensity on a product. These amplitudes are stored in memory as dotmarking profiles. The controller accesses the dot-marking profile to print dot markings onto products as desired. The user and/or the controller may also control scaling, vertical placement and overlapping of dot markings printed onto products.</p> |
