ABSTRACT:
A power supply circuit is disclosed for a ring laser having a cathode and having first and second anodes so that the ionization current between the cathode and each of the anodes are substantially equal. According to the invention, a Zener diode is electrically connected in the path of one of the ionization currents. The Zener voltage magnitude of the Zener diode is selected so as to equalize the ionization currents.
