Filed:

Jul 11, 1974

Appl. No.:

5/487754

Inventors:

Ronald G. Eguchi - Torrance CA
Michael M. Mann - Palos Verdes Estates CA
William B. Lacina - Los Angeles CA
Kay C. Crill - Long Beach CA

Assignee:

Northrop Corporation - Los Angeles CA

International Classification:

H01S 3098
H01S 310

US Classification:

331 945M

Abstract:

A single electrooptic crystalline material, having a first pair of electrodes affixed thereto along opposite faces, and a second set of electrodes affixed to alternate opposite faces, is disposed within a laser cavity. The orientation of the crystal and selection of electrode faces is such that the application of two different electric fields can achieve simultaneous mode-locking of the laser with output coupling of the optical pulses.

Abstract:

A laser beam is passed between a pair of electrodes, the switching of the beam being accomplished by generating an arc between the electrodes whereby metal vapor is ablated therefrom. The metal vapor acts to either refract or totally block the beam, in either case cutting off the laser output.
