Paper Abstract

The amplification of the Megajoule Laser will be made with a multi-pass cavity. This technical principle can generate many ghost images. In fact, beam reflections occur on lens faces, propagate in the whole system and may focus in several points. Some of these reflections can also be amplified. Furthermore, focusing points may be located near or inside optical elements and their fluence may be over the glass damage threshold. So the amplification cavity can not be realized without studying beam reflections. In consequence, OPTIS developed a new and specific software with the help and scientifical advice of the CEA/DAM.
