Apparatus for reflecting high-intensity electromagnetic radiation

AFRL has developed a plurality of optically isotropic, parallel dielectric plates of uniform thickness, mutually separated by gaps having a uniform width.

Segmented acoustic core photonic crystal fiber laser

AFRL has developed a method for which Stimulated Brillouin scattering (SBS) in a photonic crystal fiber is suppressed by doping the individual core segments such that the Brillouin frequency of each segment is sufficiently different from the neighboring segments.  Because of this, Brillouin scattered light from one core segment sees negligible gain from the other core segments, and higher power narrow-linewidth optical fiber amplifiers and lasers may be obtained.

High-energy laser atmospheric compensation and aimpoint maintenance

AFRL has developed a high-energy laser weapon system in which the high-energy laser beam itself is used to correct for atmospheric fluctuations, replacing a separate beacon illuminator system.

Tuned cladding fiber amplifier and laser

AFRL has developed a multi-mode signal core used for single transverse mode fiber amplifier and laser operation.  The core is surrounded by cladding containing irregular microstructuring that causes loss in all of the core modes except the fundamental, while maintaining robust guiding of the fundamental mode.

Multifaceted prism to cause the overlap of beams from a stack of diode laser bars

AFRL has developed an optical element for homogenizing and, possibly, concentrating the output from high-power two-dimensional semiconductor laser arrays, which has the basic shape of a convex-flat cylindrical lens with a facet cut into the convex surface for each individual semiconductor laser bar.

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.

Atmospheric Optical Turbulence Monitoring and Prediction

Guidestar’s atmospheric optical turbulence sensing technology remotely measures atmospheric turbulence strength.  Guidestar uses these measurements in combination with a proprietary model to estimate a number of localized weather parameters to support operational decision making.  In addition, Guidestar’s model can use weather forecast data to predict atmospheric optical turbulence.
