Abstract:

A mod-locked Q-switched NdYAG laser is used to generate a train of light pulses of approximately 70 picoseconds duration. The energy in these laser pulses are of the order of 2 milli-joules. The train of pulses are then passed through a switchout so that a single pulse is selected. This single pulse then strikes a chromium doped GaAs semiconductor switch which then conducts. If a high voltage supply is connected to one end of the switch and a load is connected to the other end, then the load will observe an electrical pulse which is half the amplitude of the d.c. voltage and of the order of 100-200 picosecond duration. The width of the electrical pulse is determined by the width of the laser pulse and of the characteristics of the transmission line over which the GaAs is mounted. Author
