ABSTRACT:
The output of an alkali vapor lamp for use in an optical pumping system is stabilized by use of a feedback circuit which regulates current flow from a power supply to an electronic power oscillator used to excite the alkali vapor lamp. Starting of the alkali vapor lamp is facilitated by increasing supply current to the oscillator until the alkali vapor lamp is lit.
