Abstract: An active mirror amplifier (AMA) laser module incorporating an optically transparent, rigid substrate having a plurality of cooling passages has one surface thereof disposed against a laser gain medium disk. The substrate also has a plurality of microchannels disposed near or at an outer surface thereof which is in contact with an outer surface of the disk. A cooling medium is circulated through the flow passages and the cooling microchannels to help keep the disk cool during use of the laser. This allows the laser module to operate at significantly increased power without overheating. In one preferred embodiment the disk is attached to the substrate using a pressure differential between a front surface of the disk and the pressure of the coolant. This eliminates attachment-induced thermal stresses of prior art designs and allows the laser to operate at increased power without fracturing the substrate. Pre-forming the laser medium to achieve a generally flat condition when lasing in an unrestrained condition is also disclosed, which also reduces thermal attachment stresses and allows the laser to operate at a higher power without fracturing the substrate. A preferred implementation of the laser module in constructing a power amplifier is also disclosed, as is the use of multiple optical pump sources and optical fibers for delivering the optical energy to the laser module.

Abstract: The present invention is for an apparatus and method for an actuator using an magnetohydrodynamic (MHD) pump to electrically generate a hydraulic pressure and a flow in a liquid metal, thereby causing the liquid metal to act on and extend an expansion member such as extend bellows, membrane, rolling diaphragm, or a piston in a cylinder. The resulting mechanical displacement of the expansion member may be beneficially used to exert a force, pressure, and/or to move elements of a machine. In particular, mechanical displacement (stroke) of the actuator may actuate elements of a humanoid robot, or artificial limb prosthetic, or flight control surfaces of an aircraft. The actuator may be arranged to operate bi-directionally by reversing the polarity of the electric current supplied to the MHD pump. Force exerted by the MHD actuator may be controlled by varying the electric current of the MHD pump drive current.

Abstract: A laser system including two laser amplifier modules, each comprising a solid-state laser gain material (LGM) disk, and a multi-pass optical assembly comprising a plurality of relay mirrors. The relay mirrors are grouped in two relay mirror groups. Individual relay mirrors are arranged to pass a laser beam from the first LGM disk to the second LGM disk and back to the first LGM disk, and so on. The laser beam is amplified with each pass through the LGM disk. The relay mirrors may be arranged to repeat the process of passing the laser beam to and from the two LGM disks arbitrary number of times until the desired laser beam amplification is attained. At that point, the laser beam may either released from the laser system, reflected back causing it to retrace its path through the system. This configuration increases the effective gain and improves laser power extraction.

Abstract: Methods and systems are disclosed for cooling a laser, such as a high average power (HAP) solid state laser (SSL). A coolant that has been heated from previous use can be conditioned by transferring heat from the coolant to a phase change medium. The conditioned coolant can then be re-used to cool the laser. In this manner, a low cost, lightweight, compact cooling system that generates comparatively quiescent flow at comparatively high flow rates can be provided.

Abstract: A supercharged internal combustion engine system wherein the supercharger assembly includes an ejector pump driven by high-pressure air for pumping intake air into engine combustion chamber. Included are means for sensing engine power demand and controlling the supercharging action. A compressor and an air tank for providing high-pressure air for driving the ejector pump are also disclosed. During periods of natural aspiration the ejector pump can be by-passed to reduce flow impedance. The ejector pump can use a driving nozzle with a fixed throat or a variable throat, or a lobed nozzle. Effective supercharging is achieved even at low engine speeds. One of the objects of the invention is to obtain more power from small displacement ICE and thus providing automotive vehicles with sufficient acceleration in addition to good fuel economy.
