Spatio–temporal study of an ultra-fast x-ray source produced by laser plasma in ultra-relativistic regime

The aim of the PhD is to study and develop a hard Kα x-ray source source produced by the interaction of an ultra-intense laser (10 TW - 25 fs) operating at a high repetition rate (100 Hz) with a solid target for X-ray. In particular, the PhD student will study laser matter-interaction regimes that have so far not been explored to produce Kα X-ray (I> 10^18 W/cm^2) and will carry out pump (optical) and probe (X) experiments to characterize the x-ray pulse duration (

Inducing and probing phase transition by laser in Ge:Te:Sb materials

IM2NP and LP3 labs propose to combine their capabilities and efforts for exploring and studying phase transitions in a multi-compound phase change material (Ge:Te:Sb), fabricated by ST Microelectronics. This material is being heavily studied for the fabrication of Phase Change Memories (PCM) that are among the most mature non-volatile emerging memories to allow data storage at high programing speed with enhanced endurance compared to today Flash technology.
