We report bolometric photoresponse of YBa2Cu3O7 thin film and YBa2Cu3O7ILa2CuO4 multilayers (YBCOILCO)at temperature of liquid nitrogen irradiated by a semiconductor laser diode at 0.83 microns. We develop a heat transfer model which takes into accou

Les guides obtenus par diffusion de mercure dans un substrat de tellurure de cadmium sont a gradient d’indice. L’etude des lignes noires permet d’en mesurer le profil d’indice de refraction. A partir de donnees bibliographiques reliant l’in

UV excimer etching could be an alternative method to classical lithography for the conversion of MOT planar waveguides into strip waveguides. Some preliminary results are given, which concern HgCdTe photoablation by ArF excimer laser emitting at 193

New nitrobenzene and nitropyridine derivatives have been designed and studied in powder form. Second harmonic generation (SHG) efficiencies range between 25 and 160 times that of urea. They are all transparent for wavelengths greater than 0.5 μm and

Efficient integrated frequency doubling devices transparent in the visible and near I.R. are demanded by a number of applications. The optimization of both wave interaction configurations and material intrinsic nonlinear susceptibility are successive

A UV photoablation method with an ArF excimer laser has been experimented on Mercury Cadmium Telluride alloys. We have investigated etching rate, surface quality and surface composition under several experimental conditions. We have also obtained lin
