Surface Morphological Changes Produced by KrF Laser Ablation in Polyimides.

Characterization of Expanding Laser Plasma Produced by Laser Ablation

This work is devoted to characterizing the plasma produced by nanosecond laser ablation. The expanding plasma was generated by the interaction of a home made XeCl excimer laser with a Cu target. The time-of-flight method was utilized as diagnostic tool of the plasma charged particles. By this method, in fact, we were able to measure the ion and electron currents, the charge-states and the energ...

Morphologic and histopathologic changes in the rabbit cornea produced by femtosecond laser-assisted multilayer intrastromal ablation.

PURPOSE To observe morphologic and histopathologic changes in the midperiphery of the rabbit cornea produced by femtosecond laser-assisted multilayer intrastromal ablation, determine whether this method may be used to correct myopia, and study how the cornea heals when the epithelium is not injured. METHODS The right eyes of 10 New Zealand White rabbits were used for the experiments. A 60-kHz...

Diagnostics of silicon plasmas produced by visible nanosecond laser ablation

Ž . The second harmonic of a pulsed Nd:YAG laser 532 nm has been used for the ablation of silicon samples in air at atmospheric pressure. In order to study the interaction for silicon targets, the laser-induced plasma characteristics were examined in detail with the use of a spaceand time-resolved technique. Electron temperatures, ionic temperatures and electron number densities were determined...

Acute toxicity of synthetic colloidal silver nanoparticles produced by laser ablation method to Eastern mosquitofish, Gambusia holbrooki

Considering the growing production, consumption of nanomaterials and their probable release into the aquatic ecosystems and study on the toxic effects of these materials are of critical importance to aquatic organisms. In this study, the acute toxicity of silver nanoparticles (AgNPs) produced by a physical method (laser ablation) was examined on Gambusia fish. Acute toxicity tests were planned ...
