Abstract: An optical system includes a first light source configured to generate a first light beam having a first power. The optical system includes a second light source configured to generate at least one second light beam having a second power. The second power can be greater than the first power. The optical system includes a device for a least partially co-aligning the at least one second light beam of the second power with the first light beam of the first power in a parallel or near-parallel pattern and within a region of atmospheric space so that energy will transfer from photons of the at least one second light beam of the second power to photons of the first light beam of the first power within the region of atmospheric space via Stimulated Raman Scattering (SRS).

Abstract: A directed energy system includes a gimbal assembly that includes a turret configured to rotate about a first axis, and a directed energy head coupled to the turret and configured to rotate about a second axis that is orthogonal to the first axis. The system further includes an optical fiber spooling ring comprised of a fiber cable at least partially threaded through the gimbal assembly and including a plurality of optical fibers configured to transmit optical energy. The optical fiber spooling ring includes a plurality of 360 degree rotations of the fiber cable.
