ABSTRACT:
An adjustable, constant current power supply for use in electrically pumping negative impedance gas discharge lasers is disclosed. The power supply includes a voltage regulator and a constant current power source the output of the voltage regulator which is variable and controlled being connected to the input of the constant current power source. The output from the power supply is passed through a gaseous lasing medium located within a laser tube of the gas discharge laser in order to pump to the lasing medium. Be controlling the voltage fed into the constant current power source the current output therefrom can be altered in order to effectively vary the power output of the gas discharge laser.
