  • Patent number: 11121397
    Abstract: The present invention relates to the application of a force to enhance the performance of an electrochemical cell. The force may comprise, in some instances, an anisotropic force with a component normal to an active surface of the anode of the electrochemical cell. In the embodiments described herein, electrochemical cells (e.g., rechargeable batteries) may undergo a charge/discharge cycle involving deposition of metal (e.g., lithium metal) on a surface of the anode upon charging and reaction of the metal on the anode surface, wherein the metal diffuses from the anode surface, upon discharging. The uniformity with which the metal is deposited on the anode may affect cell performance. For example, when lithium metal is redeposited on an anode, it may, in some cases, deposit unevenly forming a rough surface. The roughened surface may increase the amount of lithium metal available for undesired chemical reactions which may result in decreased cycling lifetime and/or poor cell performance.

  • Patent number: 8320426
    Abstract: An assembly for distributing laser energy is provided that is formed using a compact rigid housing with a sealed beam path contained therein. The assembly employs a monolithic housing with modular collimator and mirror switching components installed therein to reduce its size while maintaining a sealed beam path thereby reducing the possibility of contamination of the beam path. Other than the optics and mirror, there are no elements of the distribution device contained within the beam path. In one embodiment, the assembly distributes incoming energy from a single source to one or more outputs. In another embodiment, the assembly operates as a beam combiner to direct energy from one or more sources to a single output.

  • Patent number: 7982935
    Abstract: A mirror positioning assembly for use in beam switching is provided that employs a novel arrangement of the mirrors and the motors to selectively position the mirrors. The assembly is installed into the housing of an assembly for distributing laser energy where the mirrors are contained within the beam cavity and the remainder of the assembly is outside of the housing. The assembly is received in a port within the housing in a manner that allows 360° of rotational adjustment so that the mirror can be carefully aligned to insure near lossless distribution of the beam energy as it passes through the device. This arrangement keeps the electronics, motors, bearings and adjustments of the mirror switching external to the beam cavity herby reducing the number of potential contaminants contained therein.

  • Patent number: 7767145
    Abstract: A monitoring system enables in-situ monitoring of a solution enclosed within a high-pressure, closed loop environment. The monitoring system includes a calcium fluoride disk that is substantially transparent to infrared light. A hole is configured through the disk and a solution passes through the hole. Solution passing through the hole is analyzed by directing infrared light through the disk and the solution currently moving through the hole in the disk. The light exiting the disk is collected and analyzed to determine the composition of the solution through which the light passed.

  • Publication number: 20100166025
    Abstract: A high-power, short-wavelength fiber laser device combines the known advantages and well-developed technology of long-wavelength fiber lasers with the concepts of both non-linear frequency doubling and non-linear sum frequency mixing to generate visible blue laser light at a wavelength of about 427 nm. The device includes a thulium fiber laser emitting light at a wavelength of 1900 nm, and an erbium fiber laser emitting light at a wavelength of 1550 nm. The light from each of the fiber lasers is frequency doubled in respective non-linear converters, resulting in respective light sources at 950 nm and 775 nm. The resulting 950 nm and 775 nm light is combined and mixed in a non-linear sum frequency mixer to produce a single short-wavelength beam of light having a wavelength of about 427 nm.
