Abstract: A power conversion module for use with optical energy transfer and conversion system has a hemi-spherically configured housing, an array of photovoltaic chips mounted on the interior thereof, and inlet and outlet ports connected thereto. An end plate connected to the housing defines a cavity. An actively cooled high-power connector has one end connected to a fiber optic cable and the opposite end traversing the end plate and extending within the cavity. Beam forming optics within the cavity are in optical communication with the connector to disburse received optical energy in a hemispherical emission pattern of uniform flux toward an array of photovoltaic chips mounted in complementary configuration to the housing within the cavity, each chip spaced equidistantly from the beam forming optics. A heat sink within the housing has a plurality of fluid channels therethrough through which a work fluid removes heat via the outlet port.

Abstract: A method of recovery of optical fiber expended during a parabolic launch trajectory of a spacecraft is disclosed. An optical fiber adapted for transmission of high optical energy sufficient to launch the spacecraft is connected at one end to the spacecraft and is released during launching of the spacecraft. The optical fiber expended from the spacecraft is then engaged by a drum spooler following launch of the spacecraft and the fiber has been fully spooled out by the spacecraft. The optical fiber is then reeled in prior to the fiber contacting the Earth. The recovered optical fiber is then collected for processing, cleaning and rewinding for future use of subsequent series of launches for as many times as possible.

Abstract: An optical energy transfer and conversion system comprising a fiber spooler and an electrical power extraction subsystem connected to the spooler with an optical waveguide. Optical energy is generated at and transferred from a base station through fiber wrapped around the spooler, and ultimately to the power extraction system at a remote mobility platform for conversion to another form of energy. The fiber spooler may reside on the remote mobility platform which may be a vehicle, or apparatus that is either self-propelled or is carried by a secondary mobility platform either on land, under the sea, in the air or in space.

Abstract: A method of launching a spacecraft into low Earth orbit using a non-line-of-sight optical power transfer system. The method includes generating optical power at a base station and using an optical fiber to transmit the optical power generated to a launch vehicle via an actively cooled fiber spooler thereon. The optical power received by the launch vehicle is converted to another form of energy usable by the launch vehicle. The optical power is optically focused into a reaction chamber to impinge on a refractory target. A working fluid is regeneratively fed to a heat exchanger contained within the actively cooled fiber spooler. The working fluid is pre-heated within the heat exchanger and injected into the reaction chamber where the working fluid heats and expands. The exhaust is channeled through a rocket nozzle to produce thrust. In an alternative embodiment, the optical fiber expended during launch of a spacecraft is recovered.

Abstract: A fiber optic rotary joint for use in an optical power transfer system. The fiber optic rotary joint comprising a first housing element and a second housing element rotatable with respect to the first housing element. The first and second housing elements define a chamber. Optical connectors are disposed through the housing elements and have a beam expansion block positioned in the chamber. A laser is optically connected with the fiber optic rotary joint and transmits optical energy therethrough. Collimating optics aligned with the beam expansion blocks are orientated to direct the received optical energy to a position. The optical connectors and housing elements define a continuous coolant communication path with a coolant inlet and outlet. A rotary water coupling traverses through the housing elements. In an alternative embodiment, the fiber optic rotary joint also contains an actively cooled mirror positioned optically between the collimating optics.
