Abstract

TEA CO₂ lasers operate efficiently with high output energy and are expected to open up new applications in the industrial field. The TEA CO₂ laser can oscillate at a single line between 9 and 11 µm with a high peak power pulse which is strongly absorbed by a vibrational- rotational line of the organic polymer materials. The efficient ablation of the organic polymer materials such as polyether ether ketone and polyether sul- phone by single line selected TEA CO₂ lasers was successfully demonstrated.¹
