Abstract

The two high-power industrial lasers (CO₂ and YAG) cannot be focussed on a very small spot. More efficient or new laser processings can be developed by using other high-power lasers, for instance CO, chemical HF, CO or HF overtone, oxygen-iodine, or copper vapor and dye, the beams of which can be focussed on a smaller spot. As a consequence of the higher absorptivity of the metals, the better transparency of the plasma and the higher power densities available, the processing efficiency increases whereas the processing width drops. A whole array of 1 kW power range, near-IR cw lasers as well as repetitively pulsed visible lasers is already (or will be soon) available at ISL.
