Fiber active path length synchronization
AFRL has developed a method of implementing a high-power coherent laser beam combining system in which the output of a master oscillator laser having a linewidth broader than the Stimulated Brillouin Scattering linewidth of the laser signal is split into signals and fed into an array of optical fibers.
Metamaterial cathodes in multi-cavity magnetrons
AFRL has developed bulk metamaterial cathodes for multi-cavity magnetrons characterized by specific metal-thin-wire medium lattice topologies, which are used to improve the magnetron output characteristics, including faster startup times and higher microwave radiation powers.
Device for testing thin specimens in pure bending
AFRL has developed an improved test fixture to evaluate thin composite laminates commonly used in deployable space structures. The fixture is designed to impart a pure moment into the coupon, a necessary improvement to prior test methods where results are obtained by fitting material properties in a nonlinear structural analysis of the test.
Method for fabricating rib-stiffened composite structures US8435375
AFRL has developed a method for fabricating a grid-stiffened structure from fiber-reinforced composite materials. A skin is applied to a smooth, hard base tool. Ribs made of carbon-fiber tows are formed on the skin, and shallow cavities are formed between the ribs and the skin. An expansion block is placed in each of the cavities, and is held in place by an elastomeric contact adhesive having adhesive properties that are substantially diminished when the adhesive is heated to an elevated curing temperature. The assembly is then autoclave cured. After cooling, the formed structure is separated from the base tool and the expansion blocks are removed from the cavities. A grid-stiffened sandwich structure is formed by applying an outer skin over the ribs and expansion blocks, before curing the assembly. After cooling, the outer skin is removed to allow extraction of the blocks, and subsequently bonded to the ribs.
Seeded raman amplifier for applications in the 1100-1500 nm spectral region
AFRL has developed a method of generating high-power laser output in the 1100 to 1500 um spectral region having a controllable linewidth. AFRL has also developed a Raman amplifier made of one or more nested pairs of fiber Bragg grating cavities tuned to the appropriate order Stokes wavelengths.
Mosaic imager using wave front control US8390722
AFRL has developed a wave front control system (“WFCS”) that organizes the object scene into a mosaic comprised of a grid of segments and transmits each segment in a temporal sequence. The WFCS steers the light fronts emanating from each segment, one segment at a time, through a series of optical components that transmit the light fronts respectively emanating from each segment onto a digital imaging sensor. An optical recording device records each sensed segment, and the object scene is composed by assembling the recorded segments.
Deployable reflectarray antenna system
AFRL has developed a center-fed deployable reflectarray antenna system comprised of a stack of flat reflectarray panels, a deployment mast, a waveguide, and an antenna feed.
Permanent magnet structure for producing a uniform axial magnetic field
AFRL has developed a wide aperture permanent magnet structure which is useful in creating a highly uniform longitudinal or solenoidal magnetic field in the working region of the magnet. It can take the form of a cylindrical shell of permanent magnets to create a solenoidal magnetic field, or a parallel surface arrangement to create a longitudinal magnetic field.
