SYSTEM AND METHOD FOR OBTAINING LAMINAE MADE OF A MATERIAL HAVING KNOWN OPTICAL TRANSPARENCY CHARACTERISTICS

摘要

A method is described for obtaining a plurality of laminae, made of a material having known optical transparency characteristics, from an ingot made of the material, the ingot having an axis of symmetry (X), the method comprising: creating, in the ingot by use of a pulsed laser beam, a plurality of sacrificial layers with modified structure, the plurality of sacrificial layers being distributed along the axis of symmetry (X), the plurality of sacrificial layers dividing the ingot in a plurality of residual layers; subjecting the plurality of sacrificial layers to chemical etching, thereby causing a separation of the residual layers; and detaching the residual layers to produce the plurality of laminae made of the material.
