1. laser oscillator, laser output measured value is measured and is obtained in its output to the laser that penetrates, and by supplying with electric current to exciting unit, the exciting laser medium, thus carry out laser generation,It is characterized in that this laser oscillator has:

  • Current sensor, it is measured the current value that is supplied to described exciting unit;

    Upper current limit value setup unit, it sets the upper current limit value according to the laser output order value of input;

    The current instruction value setup unit, it is corresponding to the difference between described laser output order value and the described laser output measured value, and the current value that should be supplied to described exciting unit is set at current instruction value;

    Second comparator, it compares described current instruction value and described upper current limit value, and that less value is exported to first comparator as reference current value;

    AndFirst comparator, it compares described reference current value and described amperometric determination value, based on this reference current value, exciting unit is carried out the FEEDBACK CONTROL of electric current supply, will be controlled to be described reference current value to the current value that described exciting unit is supplied with.
