AQWEST, LLC — Department of Energy SBIR Phase I: 25c

Description

Inertial confinement fusion (ICF) offers to tap almost unlimited sources of inexpensive energy. This new energy source would free the U.S. from the dependence on hydrocarbon fuels, the use of which produces green-house gases (GHG). The proposed EPDL laser driver would greatly advance the ICF maturity and its transition to commercial IFE for generation of electricity. Availability of low-cost and non-polluting electric power would revolutionize transportation and manufacturing sectors, thus boosting the overall economy. Reduced dependence on hydrocarbon fuels would also reduce to size overstated importance of hydrocarbon-producing countries, thus, improving geopolitical balance. The proposed technology also offers to advance laser acceleration of nuclear particles, thus replacing the traditional mammoth-size and costly accelerator research facilities with room-size devices. Compactness and relative simplicity of laser accelerators promises to greatly reduce the cost and timelines of high-energy research, and advance new scientific discoveries. As particle research could become affordable for universities or even commercial laboratories, the U.S. would be able to maintain leadership. In Phase I, Aqwest will develop a concept for a liquid-cooled laser driver module based on Aqwest’s edge pumped disk laser (EPDL) technology for operation at high-pulse energy and high-pulse repetition rate. Cooling by liquid will accommodate increased heat load in the high-gain disks. The project will combine and scale-up EPDL technologies that Aqwest developed in previous work for the DOE and the US Army. In Phase II, we will develop the module hardware and test it to deliver an energetic laser beam.The proposed project would greatly advance the realization of the inertial confinement fusion and its transition to commercial inertial fusion energy by using Aqwet’s innovative EPDL while leveraging prior and present Department of Defense investment. In commercial applications, EPDL offers to supplant the German-made thin disk laser, which has been the dominant technology for laser material processing for the last 10 years.
