Patent ID: 6999492

Claim:
A method of providing an electrical pulse to drive a discharge chamber of a laser system, the method comprising: storing a voltage on a primary storage capacitor; applying the voltage from the primary storage capacitor to a step up transformer; outputting a stepped up voltage from the step up transformer in response to the applied voltage; applying the stepped up voltage to a first capacitor and to a second capacitor, wherein the first capacitor and the second capacitor are in parallel to each other relative to the step up transformer, wherein in response to the applied stepped up voltage the first capacitor and the second capacitor store the stepped up voltage; reversing a polarity of the stepped up voltage stored in the first capacitor; and applying the reversed polarity stepped up voltage on the first capacitor and the stepped up voltage on the second capacitor in series across electrodes of the discharge chamber, whereby a total voltage applied across the electrodes is approximately twice the stepped up voltage.
