  • Method and apparatus for producing laser pulses with high reproducibility
    Patent number: 4112392
    Abstract: A coaxial high repetition rate pulsed gas laser is provided, having a peak value pulse to pulse reproducibility better than 1% at a repetition rate of up to 400 Hz. This is accomplished by synchronizing the time evolution of the high tension laser electrode voltage with the gas break-down delay period in such a way that the laser output and stability are optimized.
