    The aim of this presentation is to show how it is possible to realize high reflectivity mirrors for optical cavities having very low optical losses. After a description of the deposition technique used, all types of loss will be listed (Transmission, absorption, scattering..). Their main origins are described and some solutions are proposed to minimize their level. The importance of the...

    Two projects of laser-Compton photon sources: Gamma ray sources for polarized positron Compact x ray sources toward application have been started in Japan. Both of the projects plan to develop 4 mirror optical cavity for laser pulse enhancement. We report status of the study of the cavities and possible plan in next a few years
