Abstract

The polymers ablation by a Q-switched carbon-dioxide laser is demonstrated and compared with that of the conventional TEA laser ablation. The 20 - 100 micrometer depth ablative etching of PET with well defined edge were successfully obtained when the strong absorbed 9R(20) line at 1078.57 cm^-1 was irradiated. It was found the ablation characteristics by a Q- switched laser was almost same as that by a TEA laser.
