Abstract
Abstract A solid state pulse generator that produces high current narrow pulses and includes a bank of parallel silicon controlled rectifier-capacitor combinations, designed for driving a gallium arsenide diode laser. A trigger circuit is connected to all the gate circuits of the silicon controlled rectifiers, through separate adjustable resistors. The adjustable resistors make it possible to simultaneously fire the silicon controlled rectifiers with a single trigger pulse.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
A device for generating a pulse through a load and comprising: a plurality of capacitors connected in parallel; voltage means for charging said capacitors; and means for simultaneously discharging said capacitors through said load, said means for simultaneously discharging said capacitors comprising a plurality of silicon controlled rectifiers connected to a first side of each said capacitor, means connecting a trigger pulse to the gate of each said silicon controlled rectifier and causing said plurality of capacitors to simultaneously discharge through said load when said trigger pulse is applied, said connecting means includes an adjustable resistor for each said silicon controlled rectifier, to thereby enable the silicon controlled rectifiers to be simultaneously triggered.
