Abstract: In a low voltage power supply, a plurality of different low voltage outputs are provided at different voltage magnitudes, the series choke of each of the output is wound on the same ferromagnetic structure (core), the number of turns in the choke of each output being different and related to the number of turns in the choke of the other outputs in the same ratio as the relationship of their voltage magnitudes, thereby to provide the same volts per turn on each of the choke windings on the common core. In a second embodiment, only some of the output chokes are driven by rectifiers fed by the transformer secondary, the remaining supplies being driven by means of transformer action through the filter chokes themselves.

Abstract: Laser systems which are pumped by an electric discharge formed in a gas are disclosed. The discharge is in the form of a vortex stabilized electric arc which is triggered with an auxiliary energy source. At high enough repetition rates residual ionization between successive pulses contributes to the pulse stabilization. The arc and the gain medium are positioned inside an optical pumping cavity where light from the arc is coupled directly into the gain medium.
