High-Power Pulsed Laser Diode Driver Utilizing Low Tempature Growth GaAs Power Switches
Agency / Branch:
DOD / USAF
The proposed research entails the development of a pulsed power driver capable of producing an electrical pulse with peak currents greater than 200 amps, peak powers greater than 200 kilowatts, and repetition rates greater than 10 kHz. MellWood Laboratories, Inc. has developed an entirely solid state system to create these high power pulses. The switching device consists of a monolithically integrated light emitting diode (LED) and a high power metal-semiconductor-metal (MSM) photo-switch. The integrated LED optically switches the MSM photoconductor. The vertical integration of an A1GaAs LED with an annealed low temperature growth A1GaAs MSM photoconductive switch allows a new class of high power devices to be developed. This high-power, compact, solid state pulsed power driver will be utilized to drive pulsed laser diodes for such applications as LIDAR.
