Significantly reduce the size and weight, and improve the efficiency of Pulsed
Power systems for High Energy Laser applications, suitable for operation as a
pod-contained payload supporting operation in the next generation of tactical
aircraft laser weapons.
The U.S. Navy has been developing a flashlamp-pumped, 1.05 micrometer Nd:Glass
rod laser design using multiple pump chambers. The current implementation
requires a pulsed power supply capable of delivering 50,000 Joules of energy in
5 milliseconds. The current system is strictly laboratory-based, weighing over
8,000 pounds with a volume of 768 cubic feet. The laser operates in a pulsed
mode with a pulse repetition frequency (PRF) of 100 Hz. Significant improvement
in pulse rate, reduction in size, weight, and power (SWaP) of the pulsed power
forming hardware, and improvement in overall laser efficiency are the goals of
this SBIR topic.
I: Develop a conceptual design for an improved efficiency, smaller SWaP pulsed
power system that meets requirements laid out in the Description. Include
methodology and potential prototype performance that will demonstrate the
proposed concept with the output pulse parameters as described. A sub-scale
hardware demonstration is desirable. The Phase I effort will include prototype
plans to be developed under Phase II.
II: Develop detailed designs based upon the Phase I with improved efficiency
and smaller SWaP that meets Navy requirements. Build a prototype pulsed power system,
according to this design, meeting intermediate parameters. Install the
prototype system in a Navy laboratory, conduct preliminary testing, and report
performance results to the Government.
III DUAL USE APPLICATIONS: Complete the SWaP reduction and ruggedization of the
overall pulsed laser system for incorporation on a Naval aviation platform
including electrical interfaces as required by MIL-STD-704F. Demonstrate the
final system and the initial scale-up of manufacturing capabilities to deliver
for a Program of Record (PoR). Transition the technology to an appropriate
platform or end user. Pulsed laser systems may have applications in materials
processing fields for cutting and welding. Other commercial applications for
the pulsed power system include those where large amounts of energy in a short
time period are required such as radar for commercial aviation and the medical
field for x-ray systems.
