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

1. 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.

2. A device as set forth in claim 1, wherein said load is an injection laser.

3. A device as set forth in claim 1, wherein said voltage means is connected in parallel to said capacitors.

4. A device as set forth in claim 1, wherein said voltage means is connected to said first side of each said capacitor.

5. A device as set forth in claim 4 wherein said load is connected at one side to a second side of each said capacitor and at the other side thereof to ground.

6. A device as set forth in claim 5, wherein said load is an injection laser.

7. A device as set forth in claim 6, wherein said injection laser is a gallium arsenide diode laser.
