Method for producing a layer of solid material

A method for producing a layer of solid material, the method comprising:

• providing a solid body having a first surface and a second surface opposite the first surface, the second surface being part of the layer of solid material;
• generating defects by means of multiphoton excitation caused by at least one laser beam penetrating into the solid body via the second surface and acting in an inner structure of the solid body to generate a detachment plane;
• generating mechanical stress in the solid body such that a crack propagates in the solid body along the detachment plane and the layer of solid material separates from the solid body along the crack,
• wherein the at least one laser beam is provided by at least one radiation source such that rays irradiated by the at least one radiation source generate the defects at predetermined locations within the solid body.
