Abstract
In this paper, the operating modes of a power supply for metal vapor lasers, in particular CuBr lasers, with pulsed charge of working capacitor were studied. A half–bridge inverter has a function of charging circuit for the storage capacitor. By varying the ratio of capacitances in the half–bridge circuit and the storage capacitor we observed different modes characterized by different charging time of the storage capacitor and amplitude of charging current. Based on requirements for a laser designed, it is useful to choose different operating modes of the inverter. When developing a high–frequency laser, it is better to use the operating mode with total discharge of capacitances in the half–bridge circuit, because it provides more time for closing the switch.
