Analytical models of transient thermoelastic deformations of mirrors heated by high power cw laser beams
We study the aberrations of massive mirrors heated by partial of intense laser beams in the coating or in the bulk. The non-uniform temperature field generated in the solid substrate induce thermoelastic deformations for which with the special assumption of axial symmetry, we give analytical models and numerical evaluations, first in the steady state, then in the transient regime Nous nous interessons aux aberrations causees aux miroirs massifs par des faisceaux laser intenses echauffant les couches reflechissantes ou la masse meme du substrat. La distribution de temperature engendree dans le substrat produit des deformations thermoelastiques dont nous donnons des modeles analytiques et des evaluations numeriques dans le cas particulier de la symetrie axiale, tout d'abord dans l'etat stationnaire, puis dans le regime transitoire
