Abstract

PURPOSE:To decrease the noises of laser rays by a mechanism wherein a collector and an emitter of a transistor are connected in series with a laser tube, and a resistor is connected between a base and the collector of the transistor and a capacitor between the base and the emitter respectively. CONSTITUTION:AC voltage generated by interrupting the output voltage of a DC power source 1 by means of a switching circuit 2 is boosted by means of the secondary winding of a transformer 3, changed into DC high voltage by means of a voltage boubler circuit consisting of diodes 4, 5, 6 and capacitors 7, 8 9, and applied to a laser tube 10. A collector and an emitter of a transistor 12 for removing ripple are connected in series with the laser tube 10, and a resistor 13 for bias is connected between a base and the collector of the transistor 12 and a capaci tor 14 between the base and the emitter.
