28 November 1983 Diamond Switches And Blumlein Pulse Generators For Kilovolt Optoelectronics

Two experiments are reported in this paper. In the first experiment we have succeeded in using natural diamond as a photoconductor excited by picosecond laser pulses to switch high voltage with 80% efficiency. The conductivity was found to be sub-linear in input light intensity, and the carrier life-time deduced to be about 1 nanosecond. In the second experiment a Blumlein pulse generator with an ultrafast opto-electronic switch is reported. The Blumlein pulse generator possesses the potentiality of yielding a pulse amplitude which can be equal to the charging voltage in an ideal case. The opto-electronic switch was fabricated from high resistivity silicon with annular aluminum electrodes. With a pulsed bias voltage of 1100 volts, the switched-out amplitude is about 900 volts, greater than the maximum voltage attainable from a standard charge line pulser generator.
