Paper Abstract

The laser induced ablative decomposition of nitrocellulose and nylon sensitized with organic dopants (Stilbene 420, Coumarin 120, and Rhodamine 6G) has been studied. Ablation with a low power nitrogen laser is hereby reported for the first time. With the addition of dyes strongly absorbing at 337 nm the photoetching rate of the pure materials can be significantly increased. A two step photochemical mechanism considering the decomposition of the polymers from excited electronic states and the energy transfer process from the dye to the polymer are discussed.
