ABSTRACT:
A control circuit for a laser system having a first and second power supply connected in parallel. A mode selector is available to the laser operator to change the operational mode of the laser system from continuous to pulse mode or vice versa, and any combination of the modes. In the pulse mode, a series of short-time voltage pulses is superimposed on a low power level laser mode by using the circuit control characteristic of the thyratron tube and shunting the ballast resistors to sharply increase the laser output power for the duration of the individual pulses.
