More Information
Summary:Laser inscribing devices for industrial production items, include a laser diode as the light impulse source and a device (10,11,1) is used for holding the temperature constant at least at parts of the pulse-generator and which includes the solid-state laser (4). The frequency of the beam pulses is controlled in order to keep the temperature constant and/or the light beam at a lower energy density internally, than at the edge region. Es wird ein Laserbeschriftungsgerät beschrieben, das eine Laserdioden-Quelle, eine Anordnung zum Aufbringen der Lichtimpulse auf der beschrifteten Fläche und eine Anordnung zur Konstanthaltung der Temperatur der Lasereinrichtung aufweist. DOLLAR A Gemäß der Erfindung wird die Frequenz der Lichtimpulse im Sinne der Konstanthaltung der Temperatur variiert, und/oder es wird ein Strahl mit im Zentrum geringerer Energie als am Rand erzeugt.
