ABSTRACT:
Controlled avalanche driver circuits and apparatuses for gas lasers. One embodiment typically delivers short, rapid, high voltage ionizing pulses in combination with an electric field whose magnitude is too low to sustain a normal glow discharge. The plasma is typically impedance matched with the pulse-forming network. Pre-ionization pulses may be generated. The circuits enable very high power, stable lasers.
