Filed:

Mar 13, 2003

Appl. No.:

10/389355

Inventors:

Anthony Michael Baca - Albuquerque NM, US
Luis M. Ortiz - Sante Fe NM, US
Thomas A. Crow - Albuquerque NM, US
Donald W. Wichers - Albuquerque NM, US

Assignee:

Saltech Corporation - Albuquerque NM

International Classification:

C02F001/32

US Classification:

210 97, 2101981, 4221863, 422 62, 250437

Abstract:

A water-borne hazard detection and water treatment system includes sensors (e. g. , flow rate, microorganism detectors, and chemical detectors) and can be microprocessor controlled. Microorganisms and/or chemicals are detected within a water distribution system. Treatment areas can be deployed at various stages along a water distribution system. Water entering/passing through a “treatment area” are subjected to light emanating from an ultraviolet laser. UV treated water is provided to its intended point of use after treatment. Filtration can be deployed around input and/or output locations of a system. The system is networkable for communication to remote monitoring agencies (e. g. , command and control units) through wired and/or wireless network communications and devices. Networked monitoring and assessment enables rapid deployment of counter measures within affected water distribution systems and populated communities. Emergency distribution shut-off through the distribution network can be based on input from distributed sensors.

International Classification:

C02F 1/32

US Classification:

96224, 210748, 210 97

Abstract:

A fluid-borne (e. g. , water, air) biological and chemical hazard detection and treatment system can include sensors (e. g. , flow rate, contaminant detectors), treatment using ultraviolet laser-emitted light, can be microprocessor controlled and can communicate and be controlled over data networks. Treatment and detection systems can be deployed at various stages along a fluid distribution system, allowing for protection coverage and redundancy. During treatment, fluid enters into and/or passes through a “treatment area” wherein the fluid is subjected to light emanating from a laser at wavelengths within the ultraviolet range. DNA for microorganisms contained within fluid (including blood) are reactive to laser light as they pass through treatment areas and are rendered un-infective. Treatment systems can be staged in close proximity, providing more than one treatment area and associated light sources to a fluid stream. Such staging can provide for concentrated redundancy prior to its delivery to the intended point of use.

International Classification:

H01S 3/06
C30B 29/32
C30B 19/12

US Classification:

372 41, 117 54

Abstract:

A laser gain element including an undoped layer of a monoclinic double tungstate (MDT) crystal, and a method of forming a laser gain element are provided. The laser gain element includes a layer of doped MDT crystal adjacent to the undoped layer, the doped MDT layer including a pre-selected concentration of rare earth ions. The layer of doped MDT crystal has an absorption peak at a first wavelength and an emission peak at a second wavelength longer than the first wavelength; and the layer of doped MDT crystal has a fluorescence emission with a weighted average at a third wavelength shorter than the first wavelength. A laser resonator cavity formed with a plurality of composite gain elements as above is also provided.
