Haiyin Y Sun

US Patent:

6612719, Sep 2, 2003

Filed:

Aug 26, 2002

Appl. No.:

10/228318

Inventors:

Matthew O. Richardson - Grass Valley CA
Haiyin Sun - Citrus Heights CA
Christopher J. Kruger - Auburn CA
Daniel W. Callen - Auburn CA

Assignee:

Coherent, Inc. - Santa Clara CA

International Classification:

F21V 500

US Classification:

362268, 362331, 362332, 362336, 372 43, 359668, 359641, 235454

Abstract:

An illumination apparatus includes a semiconductor laser providing light-output in first and second mutually perpendicular axes. The light-output propagates in a direction mutually perpendicular to the first and second axes. An optical system is arranged cooperative with the semiconductor laser to focus the light-output inn the first and second axes at respectively first and second focal points spaced apart in the propagation direction. At a plane intersecting the first focal point perpendicular to the direction of propagation, the focussed diode-laser light-output is formed into a line of light having a width in the first axis and a length in the second axis.
