Study of a compact three-electrode oscillator-amplifier excimer laser system
Autor: Daniele Murra, Francesco Flora, C. Petrucci, Sarah Bollanti, Olivier P. Uteza, O Di Lazzaro, Tommaso Letardi
Publikováno v: Optics Communications. 132:565-573
We present the design and performance details of IANUS, a three-electrode XeCl excimer laser operated as a power-oscillator power-amplifier system. The oscillator, equipped with a generalised self-filtering unstable resonator, delivers a very low div

Laser-Induced Damage in Optical Materials: 2009, 2009, France. pp.75041N
The use of large Ti:Sapphire crystals in ultra fast high peak power laser amplifiers makes crucial the problem of crystal laser induced damage. These works aim to quantify the laser induced damage threshold (LIDT) of Sapphire and Ti:Sapphire crystals

Surface intrinsic fluorescence spectroscopy of proteins using a UV linearly polarized pulsed laser beam
Autor: S. Yapoudjian, Vladimir I. Marine, Marc L. Sentis, Margarita G. Ivanova, Olivier P. Uteza
Publikováno v: International Conference on Atomic and Molecular Pulsed Lasers III.
The proposed new interfacial spectroscopic method allows to measure the fluorescence emission spectra of the two tryptophans of the Bovine Serum Albumin (BSA) during its adsorption at the air/water and egg-lecithin (egg-PC)/water interfaces, using an

Excimer laser decontamination
Autor: Philippe Ch. Delaporte, Wladimir Marine, Olivier P. Uteza, Marc L. Sentis
Publikováno v: International Conference on Atomic and Molecular Pulsed Lasers III.
The application of excimer laser ablation process to the decontamination of radioactive surfaces is discussed. This technology is very attractive because it allows to efficiently remove the contaminated particles without secondary waste production. T
