| Popis: | Laser damage studies are made on a phase mirror used for laser beam shaping in high power laser applications. The phase mirror is composed of a glass substrate with defined patterns to encode a phase, on top of which a multilayer mirror is deposited. We describe in this paper the LIDT obtained (at 1064nm, 6ns) and the laser damage test procedure, adapted to the geometry, that has been used. A morphologic analysis of the damage sites is made with Nomarski and Atomic Force Microscopy, to obtain information on the damage initiation and its localization on the structured component. The results are completed with simulations of the electric field within the multilayer by using a wave propagation computer code. We obtain localization and values of the light intensification occurring in the structure, that we correlate to experimental measurements. |
