LOW VOLTAGE LIGHTING METHOD OF HIGH POWER LASER TUBE

摘要

One terminal of induction coil wound around a laser tube to lower the breakdown voltage of a laser tube is connected to a cathode of a tube. A reverse current flowing to a main circuit is blocked by a high voltage-high current diode (Ds). The triggering circuit lowers the breakdown voltage about 1/3 of conventional triggering circuit and decreases the EMI or the EFI noises. The lowest breakdown voltage appears when the anode is wound by the induction coil.
