Continuous Wavelength Tunable Laser Source With Optimum Orientation Of Grating And Gain Medium
Continuous Wavelength Tunable Laser Source With Optimum Orientation Of Grating And Gain Medium
US Patent:
8467430, Jun 18, 2013
Filed:
Sep 20, 2011
Appl. No.:
13/237461
Inventors:
David P. Caffey - San Diego CA, US
Michael Radunsky - Poway CA, US
Edeline Fotheringham - San Diego CA, US

Assignee:
Daylight Solutions, Inc. - San Diego CA
International Classification:
H01S 3/08, H01S 3/10
US Classification:
372102, 372 20, 372 92, 372 98
Abstract:
An external cavity laser assembly () that generates a light beam () includes a gain medium () and a diffraction grating (). The gain medium () has a growth direction (C), a fast axis (A), a first facet (A), and a second facet (B) that is spaced apart from the first facet (A). The gain medium () emits from both facets (A) (B). Further, a beam polarization () of the light beam () emitting from the second facet (B) is perpendicular to the growth direction (C) and the fast axis (A). The grating () includes a plurality of grating ridges (A) that are oriented parallel to the beam polarization (). Moreover, each of the grating ridges (A) can have a substantially rectangular shaped cross-sectional profile.

US Patent:
2013024, Sep 19, 2013
Filed:
Mar 11, 2013
Appl. No.:
13/793197
Inventors:
David P. Caffey - San Diego CA, US
Assignee:
DAYLIGHT SOLUTIONS, INC. - San Diego CA
International Classification:
H01S 5/024, H01S 5/02
US Classification:
372 36, 372 3804
Abstract:
A laser assembly () that generates a beam () includes a gain medium () having a first facet region () that includes a first facet (), a second facet region () that includes a second facet (), and an intermediate region () that separates and connects the facet regions () (). Additionally, the gain medium () includes a substrate layer () and a core layer () that extend between the facets () (). The gain medium () is designed so that when current is directed to the gain medium, (i) current flows through the core layer () in the intermediate region () to generate the beam (), and (ii) current does not flow through or flows at a reduced rate through the core layer () in one or both facet regions () ().

International Classification:
G02B 27/20, H01S 3/10
US Classification:
362259, 372 28
Abstract:
A laser source assembly for providing an assembly output beam includes a first emitter, a second emitter, and a third emitter. The first emitter emits a first beam along a first beam axis that is substantially parallel to and spaced apart from an assembly axis. The second emitter emits a second beam along a second beam axis that is substantially parallel to and spaced apart from the assembly axis. The third emitter emits a third beam along a third beam axis that is substantially parallel to and spaced apart from the assembly axis. The first beam axis, the second beam axis and the third beam axis are positioned spaced apart about and substantially equidistant from the assembly axis.for
