Toward IFE Oriented Laser Chains: Cryogenically Cooled Ytterbium Doped Materials

With the aim to set up Inertial Fusion Energy (IFE) driver, we develop the properties of the Ytterbium doped materials and the problems met when designing such a system: essentially thermal management and ASE gain depletion. We after present the experimental results obtained using sesquioxide Yb(3+) doped ceramics at cryogenic temperature. We also propose a solution for minimizing the ASE problem.
