Abstract:
1. An excimer or molecular fluorine laser system, comprising: first and second discharge chambers each being filled with a gas mixture, each of said first and second discharge chambers containing a pair of electrodes for energizing the gas mixture and outputting an optical pulse; circuitry for providing separate, sequential excitation pulses to said first and second discharge chambers; and a real time jitter compensation circuit, said jitter compensation circuit receiving an input corresponding to a measured laser parameter which exhibits pulse to pulse variations, said jitter compensation circuit generating a variable delay signal in response to the received input and supplying the signal to said circuitry to control the relative timing of the excitation pulses delivered to the first and second discharge chambers on a real time pulse to pulse basis, and wherein said laser parameter is selected from one or more of the voltage on a storage capacitor, a reset current and a core magnetization.
