Abstract: An object redirection system may generate a high-resolution three-dimensional map of a surface of a target. Based on the map, the system may identify locations on the target's surface and direct energetic pulses toward the target at the locations. The system may continuously update the map of the target and continue emitting pulses at the target with reference to the map in order to achieve a desired velocity of the target within a desired timeframe.

Abstract: A system has a plurality of spacecraft in orbit around the earth for collecting energy from the Sun in space, using stimulated emission to configure that energy as well defined states of the optical field and delivering that energy efficiently throughout the region of space surrounding Earth.

Abstract: A solid state laser medium comprising at least one cooling element, i.e. cooling element, in contact with and alternating in series with at least one gain element. At least one cooling element and at least one gain element are joined at an interface having a center point, wherein the interface is physically modified at the interface such that the heat transfer coefficient at the interface decreases radially from the center point of the interface. The modified interface promotes thermal transfer from the gain element in the axial direction, in such a manner as to reduce thermal distortion affecting optical properties of the laser. Concentric radially disposed barriers to heat flow that hinder heat flow in the radial direction may be added within the gain element to further reduce thermal distortion within the laser medium.
