h-v monitor, current protect, and ballast, for stable laser oscillation (May 1972) (Engineering Materials). [25 drawings]
Drawings are given for an interface and control device for the operating high voltage supplies for a stabilized CO/sub 2/ laser. The laser has a symmetric discharge with the center cathode at a high negative voltage and the anodes close to ground potential allowing mirror placement and monitoring hardware in that area with minimum electrical hazard. In series with each anode at each end of the laser is a constant current power supply to hold the discharge current constant. The high voltage supplies are standard supplies paralleled and isolated from each other to provide the current required for the discharge. The maximum current allowable for each half is approximately 60 milliamperes. The design requires that the operating gas discharge be chosen for operation in the positive resistance region. The maximum compliance of the constant current regulating supplies is 300 volts and there are diode protective networks to prevent over or reverse voltages from damaging them.
