Abstract

Experimental studies of the fabrications of polymer and non-polymer organic thin films by laser ablation are discussed. We succeeded in fabrication of crystalline thin films of polytetrafluoroethylene (PTFE) by F₂ laser (157nm) ablation. As an example of the application of the PTFE thin film, we fabricated PTFE thin films containing semiconductor CdTe microcrystallites, which show a 3rd-order optical nonlinearity. Non-polymer organic thin films fabricated by KrF laser (248nm) ablation, such as copper-phthalocyanine (CuPc) and 4-dialkylamino-4'-nitrostilbene (DANS), also showed crystallinity and little change in their composition when reducing the laser ablation fluence close to the ablation threshold fluence of -20mJ/cm².
