Paper Abstract
In this paper, the destruction of the mirrors under continuous wave (cw) laser irradiation is studied. The existence of a critical temperature, at which the mirrors are destroyed, has been already established. But two damage processes are associated with this temperature: the threshold and the ageing. The threshold occurs when the mirror reaches this critical temperature at the steady-state. The threshold essentially depends on the thermal conductivity of the substrate. The ageing processes begin after the thermal equilibrium time and depend essentially on the physical properties of the thin films. The ageing procedure proposed is used in order to compare the mirrors lifetime.
