Abstract
Laser photoablation of a variety of organic polymer films was observed at wavelengths of 193nm, 248nm and 532nm. Polydiacetylenes showed a very high intensity dependence of the etch rate. No degradation was observed in the remaining layers of the film except for visible (532nm) irradiation. Polystyrene films showed a high sensitivity of the ablation characteristics on dye doping. For the example of a polycarbonate film we fitted the ablation data to a model adapted from Magan et al. [1].
