Filed:

Nov 4, 1988

Appl. No.:

7/267264

Inventors:

Michael O. Hale - Bellevue WA

Assignee:

AMOCO Corporation - Chicago IL

International Classification:

C12N 1300
C12M 142

US Classification:

435 2

Abstract:

A method and apparatus for altering pathogenic microorganisms and viruses in a bodily fluid. The microorganisms or viruses to be altered are tagged by immunofluorescent antibodies and placed in an illumination area where each of them fluoresces. A portion of the fluorescent radiation is received by an optical amplifier which amplifies the fluorescent radiation and redirects the fluorescent radiation back onto the cell from which it originated. The resonant cavity of the optical amplifier can be either a linear cavity or a ring cavity.

Amoco Corporation - Chicago IL

International Classification:

H01S 3098

US Classification:

372 18

Abstract:

A method and apparatus for automatically maintaining the length of a laser cavity in a laser system in an optimum single length mode regardless of changes of frequency in the dispersive optics feedback, by sensing a group of pointing directions of a laser beam over a determined range of operating conditions, determining the average pointing position of the laser system for the group of sensed pointing directions and adjusting the length of the laser cavity to conform the pointing direction of the laser system to the average pointing direction.
