Laserdot has been working on adaptive optics systems for over 15 years. The first applications were about laser beam control. This has led to the first kind of deformable mirrors we use for the correction and dithering of the wavefront. These mirrors may be cooled depending on the laser beam power. Lately, with the participation of different European institutions, this knowledge has been applied to astronomical imaging. The `Come On' project showed how interesting such a technique is. `Come On Plus,' the project to be carried out, will certainly improve these first results. At the same time, jointly with Francois Roddier and for astronomical purposes too, Laserdot has achieved some bimorph mirrors which are to be used with a curvature sensor. This paper aims to oversee the mechanical components which have been designed for these different studies.
