A method and device for producing subsurface markings in a transparent material body by focusing a pulsed laser beam in the interior of the material body so that the laser beam exceeds the destruction threshold of the material body to produce a permanent marking. Individual markings form a freely selectable internal engraving as a result of a relative movement between the laser beam and the material body. The laser pulse is varied with respect to its pulse energy (P) by means of a discharge pulse (E) that has an adjustable time delay from an excitation pulse (A). Markings that have varying optical properties depending on the pulse energy (P) are produced in this fashion.
