摘要：

Products of UV laser ablation of polymers were collected by deposition in vacuum on a quartz crystal microbalance. The angular distribution and yield of the deposition were measured as a function of the experimental conditions (wavelength, fluence, pressure and polymer). Reabsorption of the laser energy by the desorbed gas products plays an important role, by decreasing the mean size of products. At threshold fluence, a short wavelength (193 nm) desorbs larger products. Aromatic polymers give higher yields of deposition. © 1990.
