KrF-excimer laser ablation of sintered-powder PTFE targets is successfully used for the deposition of high-quality thin films. The mechanism is based on the high extinction of the pressed-powder targets which causes more efficient dissipation of the incident laser-light energy. As a result, a strongly forward-directed jet of PTFE particles is generated. This jet is investigated by means of a gated ICCD-camera. While the expansion of the visible plume starts with the laser pulse and lasts for about , the particle jet can be observed within a time interval between about and more than after the laser pulse.
