Title: Method for reducing energy losses in laser crystals

Full Record
Other Related Research

Abstract

A process for reducing energy losses in crystals is disclosed which comprises: a. heating a crystal to a temperature sufficiently high as to cause dissolution of microscopic inclusions into the crystal, thereby converting said inclusions into point-defects, and b. maintaining said crystal at a given temperature for a period of time sufficient to cause said point-defects to diffuse out of said crystal. Also disclosed are crystals treated by the process, and lasers utilizing the crystals as a source of light.

Algae cultivation systems and methods with reduced energy loss

Patent Hazlebeck, David A.

An open raceway algae cultivation system includes a channel configured to contain an algae cultivation fluid. The channel includes a contraction zone having a width and a depth. A pump is configured to circulate the algae cultivation fluid in the channel. A width of the contraction zone decreases leading into the entrance of the pump and a depth of the contraction zone is greater than a depth of at least a portion of the channel located outside of the contraction zone.

Turbine and method for reducing shock losses in a turbine

Patent Ristau, Neil

A turbine includes a rotor and a casing that circumferentially surrounds at least a portion of the rotor. The rotor and the casing at least partially define a gas path through the turbine. A last stage of rotating blades is circumferentially arranged around the rotor and includes a downstream swept portion radially outward from the rotor. A method for reducing shock losses in a turbine includes removing a last stage of rotating blades circumferentially arranged around a rotor and replacing the last stage of rotating blades with rotating blades having a downstream swept portion radially outward from the rotor.

Segmented superconducting tape having reduced AC losses and method of making

Patent Foltyn, Stephen R [Los Alamos, NM]; Jia, Quanxi [Los Alamos, NM]; Arendt, Paul N [Los Alamos, NM]; ...

A superconducting tape having reduced AC losses. The tape has a high temperature superconductor layer that is segmented. Disruptive strips, formed in one of the tape substrate, a buffer layer, and the superconducting layer create parallel discontinuities in the superconducting layer that separate the current-carrying elements of the superconducting layer into strips or filament-like structures. Segmentation of the current-carrying elements has the effect of reducing AC current losses. Methods of making such a superconducting tape and reducing AC losses in such tapes are also disclosed.
