Photoassociative excitation spectroscopy of excimer molecules
… states was explored as a tool for the study of excimer molecules. Since the repulsive nature of the ground state constrains collision pairs to large internuclear transitions, bound $\gets$ free excitation spectra contain more structure than the bound $\to$ free fluorescence spectra for the same …

Dynamik der Schichtabscheidung von Keramiken mit KrF-Excimer-Laserstrahlung
The dynamic during pulsed laser deposition of Al2O3, BaTiO3 and ZrO2 is investigated. The expansion of the laser induced plasma is analytically described as a function of the processing variables and material parameters, considering elastic or inelastic collisions between the ablated particles and …

Diatomic excimer dynamics in microplasma lamps and alkali lasers
The dynamics of diatomic excimers - electronically excited molecules having dissociative ground states - generated in alkali-rare gas mixtures and low temperature microplasmas have been pursued and the experimental and computational results are presented here. This work focuses on the Cs-rare gas …

Stretchable, multimodal, large-area sensor arrays fabricated using excimer laser photoablation technologies
… electrode layers and as in-situ masks for excimer laser photoablation. This approach reduces the number of processing steps and photomasks, is scalable for large-area arrays, and is adaptable for a variety of materials and designs. This novel process is used for interconnect and sensor …

Experimental study of rare-gases excimer VUV system and H2 Lyman-bands calibration
An electron impact rare gas excimer vacuum ultra-violet experimental system is custom-designed and tested using an argon and H2 mixture. An electron flooding system, i.e. filament, is used as the hot electron source. A SiNx membrane is applied as the entrance foil separating the high vacuum chamber …

An investigation of the fluorescence emitted by arterial intimas during irradiation by a XeCl excimer laser
Laser angioplasty of occluded arteries has been limited by the unacceptably high rate of vessel wall perforation. To overcome this limitation, fluorescence spectroscopy of arterial wall tissue has been proposed as a technique to discriminate between normal and atherosclerotic arteries and thereby …

An attampt to measure the electron temperature of a Xenon Chloride excimer laser discharge plasma by Thomson scattering
… A short, 532 nm pulse was injected into the excimer laser and the backscattered light was analysed. The scattered beam was imaged onto the entrance slit of a spectrometer and the spectrally dispersed output was collected by either a streak camera or a photomultiplier array. The injection …

Effect of Mitomycin C with different application method on rabbit corneal wound healing process after Excimer laser photortherapeutic keratectomy
… haziness and keratocyte proliferation after Excimer laser phototherapeutic keratectomy in rabbit. PTK was performed in both eyes of 18 New Zealand white rabbits using Technolas 217™. After laser removal of the epithelium(40 um depth with the optical zone 6.0mm), stromal ablation of 100 um …
