An approach to the ejection mechanisms of Li atoms from pulsed excimer laser ablation of a LiNbO3 target

A nonequilibrium kinetic model is used for predicting the time evolution of the Li atom concentrations ~ground and excited states! in the plasma produced by excimer laser ablation of a LiNbO3 target. The model predicts a very high ionization degree ~;0.97! that agrees well with the one obtained experimentally ~;1!. These results together with the prediction of high ~and close to local thermodyn...

Modeling the thermal - 8 to - plasma

Excimer laser ablation of metals starts as a thermal process in the -1-J/cm2 fluence range and makes a rapid transition near 5 J/cm2 to a highly ionized plume (for IO-ns pulses). The 1-5-J/cm2 range is of particular interest because it overlaps the irradiance range used to fabricate high-temperature superconductors, diamondlike carbon films, and conducting Cu films. Covered here are analyses ai...

Laser Ablation of Carbon Fiber Reinforced Plastics: Laser-Ionization TOF Mass Spectrometric Study

Neutral fragments from a nanosecond KrF excimer laser-ablated carbon fiber reinforced plastic (CFRP, carbon fiber/epoxy resin composite) were investigated by laser-ionization time-of-flight (TOF) mass spectrometry in order to explore the laser ablation dynamics of CFRP. The neutrals were detected after the post-ionization by an ArF excimer laser pulse at variable delay times, td, relative to th...

308-nm excimer laser plus topical calcipotriol in the treatment of vitiligo; A single blind randomized clinical study

Background: There is a large variety of therapeutic agents for the treatment of vitiligo, but it still remains a challenge. Narrow-band UVB phototherapy and 308-nm excimer laser have been shown to be safe and effective for the treatment of vitiligo. Topical calcipotriol has recently been reported to enhance the efficacy of phototherapy, especially 8-methoxypsoralen plus UVA (PUVA). The goal of ...

Gas chromatographic-light microscopic correlative analysis of excimer laser photoablation of cardiovascular tissues: evidence for a thermal mechanism.

The present series of experiments used gas chromatography to identify vapor-phase photoproducts liberated during excimer laser irradiation of cardiovascular tissues in air and blood. In air, laser beams produced from ArF (193 nm) and XeF (351 nm) excimer laser gas mixtures were delivered to samples of myocardium and atherosclerotic coronary arterial segments through the wall of a quartz cell, u...
