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.
