Power supply for negative impedance gas discharge lasers
An adjustable constant current power supply for a negative impedance gas discharge laser is described comprising: means for providing constant output of current, means connected between the constant current providing means and the gas discharge laser for matching the current output of the constant current providing means with lasing requirements of the gas discharge laser, the constant current providing means providing electrical energy to pump the gas discharge laser; and means electrically connected to the constant current providing means for feeding a variable controlled voltage to the constant current providing means the variable voltage altering the constant output of current over a preselected range feedback circuit means for providing a control signal to the variably controlled voltage feeding means; such that output power of the gas discharge laser varies with the output of current from the current providing means.
