High-voltage pulse modulator with a nanosecond rise CONTROL electro-optical shutter AS Pockels cell

摘要

The invention relates to a high-voltage pulse technique and is intended to control the electro-valve a Pockels cell. It can be used as part of a solid-state laser operating in Q-switched mode. The technical result consists in expanding the functional capabilities of existing modulators by connecting the second controlled high voltage power supply. At the same time in a single modulator implemented two control modes «switch-on» and «switch-off». The modulator includes a first power source shunt capacitor connected to the plus two, series-connected semiconductor switches with galvanically isolated control circuits; clock generator is supplied to the control circuit; a discharge resistor connected in parallel semiconductor switches connected to a minus sources; electro-optical shutter, a first terminal of which is connected to the junction semiconductor switches and the second plus second controllable source, shunted by a capacitor, wherein the disadvantages of both sources are connected to a common bus. To reduce the voltage of the first power semiconductor switches can be replaced Marx generator.
