    摘要: A coaxial type laser oscillator to carry out excitation of laser medium gas by voiceless discharge with high performance.The laser oscillator is constructed in such a manner that at least a pair of ring-shaped electrodes are disposed on and around the outer peripheral surface of the discharge tube, and alternating current voltage is applied across the electrodes so as to enable the voiceless discharge to be generated in the discharge tube and to output laser beam outside the oscillator.

    摘要: A pulse electric power unit according to this invention performs a switching control of output current from a direct current power supply by means of an electronically-operated switch to thereby effect a voltage conversion for producing a voltage having the polarity opposite to that of a direct current voltage by causing a direct current voltage of the direct current power supply to vary, or producing a voltage having the same polarity as that of the direct current voltage by boosting and/or unboosting the direct current voltage or producing a voltage having the same polarity as that of the direct current voltage by boosting the direct current voltage. This pulse electric power unit can prevent improper current from occurring by means of a reverse-current blocking diode for blocking a capacitor from being discharged and can output pulse current having a quick rise/fall characteristic.

    摘要: A laser perforator device is controlled with respect to laser power and duty ratio in a manner so as to produce uniform perforations at a selected pitch in a workpiece, such as, a travelling plastic or metallic web. The speed of the workpiece is detected and is combined with the values for the desired pitch and duty ratio to produce pulses of the correct duration. These pulses control a switch that passes a laser level control signal to the laser that perforates the workpiece. The laser level control signal responds to the speed to provide uniform energy density to the workpiece.
