L''A(c)laboration de nouveaux revAatements interfA(c)rentiels multicouches est motivA(c)e par la demande de l''astrophysique solaire et par le dA(c)veloppement de nouvelles sources de rayons EUV (source A gA(c)nA(c)ration d''harmoniques d''ordre A(c)levA(c), laser X, rayonnement synchrotron). Nous avons A(c)tudiA(c) et dA(c)veloppA(c) diffA(c)rents systA]mes multicouches possA(c)dant A la fois des propriA(c)tA(c)s optiques optimisA(c)es (rA(c)flectivitA(c) et/ou bande passante) et une bonne stabilitA(c) temporelle et thermique pour la gamme de longueurs d''onde comprise entre =30 nm et =50...

These proceedings comprise of invited and contributed papers presented at the 13th International Conference on X-Ray Lasers (ICXRL 2012) which was held 11 15 June 2012 in Paris, France, in the famous Quartier Latin, inside the historical Center of Cordeliers. This conference is part of a continuing series dedicated to recent developments and applications of x-ray lasers and other coherent x-ray sources with attention to supporting technologies and instrumentation.
New results in the generation of intense coherent x-rays and progress towards practical devices and their applications are...
