Abstract
A laser energy microinscribing system, including a semiconductor excited Q-switched solid state laser energy source; a cut gemstone mounting system, allowing optical access to a mounted workpiece; an optical system for focusing laser energy from the laser energy source onto a cut gemstone; a displaceable stage for moving the gemstone mounting system with respect to the optical system so that the focused laser energy is presented to desired positions on the gemstone, having a control input; an imaging system for viewing the gemstone from a plurality of vantage points; and a rigid frame supporting the laser, the optical system and the stage in fixed relation, to resist differential movements of the laser, the optical system and the stage and increase immunity to vibrational misalignments.
