1. laser processing device;

  • Comprise that mainly a driving source is the pulse oscillation solid-sate laser apparatus of laser diode;

    Wherein said laser diode is launched light beam in the main energy absorption spectrum of solid state laser active medium;

    It is characterized in that, comprising;

    a measuring instrument, the laser output of full-time measuring radiation;

    The maximum judgment means, the maximum of particular monitored cycle in the measured laser output valve of acquisition during laser beam radiation, this particular monitored cycle is shorter than the whole period of laser beam radiation, and wherein this particular monitored cycle finished before laser output stops;

    The error judgment device, after a period of time in predetermined particular monitored cycle, more said maximum is kept watch on the specific laser output valve of level with conduct, and judges whether said maximum is within the specific scope;

    With the fault filming apparatus, display alarm content and while stop the operation of said pulse oscillation solid-sate laser apparatus at least when said error judgment device judges that said maximum is in outside the said particular range.
