Abstract

Laser processing methods based on projection of amplified images provide significant benefits compared to scanning based methods in applications with variable high resolution information. Using the Texas Instrument Digital Micromirror Device (DMD) as a Variable Mask, an image amplification architecture is presented that provides pulse energies (50 ~ 250mJ) and peak powers necessary to process large areas (several cm² ) with variable high resolution information. The seed lasers and the amplifiers used in the architecture are pulsed Nd:YAG systems.
