Energy recovery of parasite pulses based on LFR topology

Energy recovery of narrow, high power pulses based on loss free resistor (LFR) topology is described. A novel LFR realization based on transmission lines is presented. The purpose of this LFR is to recycle high voltage, high power (up to 20 kV, 1 MW) parasite pulses which arise in a copper vapor laser. These pulses consume up to 40% of the total power of the system. A low voltage (170 V) LFR of this type has been constructed and operated at recycling efficiency of 85%.<>
