摘要
The circuit is described of a high-frequency pulse generator to supply a solid-state Bragg diffraction modulating shutter with two opposing spatially separated traveling modulated ultrasonic (US) waves. When externally triggered, the generator delivers pulses of 1 msec duration with a carrier frequency 25-30 MHz. The maximum output power is similar 60 W. The generator provides for three operating modes of the shutter: unmodulated traveling US waves, traveling US waves modulated by microsecond pulses, and traveling US waves modulated by pulses from an external generator.
