Abstract : A method for replicating laser mirror surfaces is described which comprises careful preparation, as, for example, by single point diamond turning, on a master block, of a master surface having the contour corresponding to the desired laser mirror surface, vapor depositing onto the master surface a thin metallic layer, and vapor depositing the laser mirror faceplate material to the desired thickness. The selected master block material has a coefficient of thermal expansion mismatch with that of the deposited faceplate material so that the master block shrinks and separates away from the deposited faceplate upon cooldown from the vapor deposition temperature.
