| Abstract |
The present paper describes an all-solid-state high voltage nanosecond pulse generator for pumping a copper vapor laser. The main feature of this device is using a high voltage switch composed of a stack of insulated gate bipolar transistors (IGBT), what makes it compacter and more cost effective than traditional systems based on thyratrons and vacuum tubes. A fast transformer circuit provides highly synchronous on/off control of the IGBT stack. Two-stage magnetic pulse compressor is used to enhance the system efficiency.
The developed laser pumping system generates current pulses with amplitude of 230 A and rise time of 30 ns at pulse
repetition rate of 15 kHz. Average laser output power of 13 W was obtained under these pumping conditions. |
