US Patent:

6685319, Feb 3, 2004

Filed:

Sep 20, 2001

Appl. No.:

09/960163

Inventors:

Jason Watson - San Jose CA
John K. Shimmick - Belmont CA

Assignee:

Visx, Incorporated - Santa Clara CA

International Classification:

A61B 300

US Classification:

351219

Abstract:

Systems and methods verify and/or correct optical errors of an eye. A plan is generated for a corrective procedure of the eye from a measured optical error, and a verification lens is formed based on the measured optical error to verify the procedure plan. Alignment of an aperture (with a size selected to correspond to the size of the pupil) with the eye while measuring optical properties of the eye through the verification lens improves verification accuracy, as does mounting of the verification lens and aperture to the patient with a trial frame.

US Classification:

372 50124, 372 5011, 372 21, 372 22, 372100

Abstract:

Arrays of vertical extended cavity surface emitting lasers (VECSELs) are disclosed. The functionality of two or more conventional optical components are combined into an optical unit to reduce the number of components that must be aligned during packaging. A dichroic beamsplitter selectively couples frequency doubled light out of the cavity. In one implementation the dichroic beamsplitter includes at least one prism.

Appl. No.:

11/602147

Inventors:

Bojan Resan - San Jose CA, US
R. Russel Austin - Cool CA, US
Jason P. Watson - San Jose CA, US

Assignee:

Coherent, Inc. - Santa Clara CA

International Classification:

G02B 26/00

US Classification:

359237

Abstract:

An optical pulse-shaper includes a prism, a delay line having positive optical power and a reflective spatial light modulator. In one arrangement the delay line has a selectively variable optical path length for accommodating pulses of different spectral bandwidth and positive optical power is provided by a concave mirror. In another arrangement, the delay line includes a zoom-mirror arranged to provide selectively variable optical power for accommodating pulses of different spectral bandwidth.

Appl. No.:

Inventors:

Thomas C. Hasenberg - Campbell CA, US
Jason P. Watson - San Jose CA, US

Assignee:

Coherent, Inc. - Santa Clara CA

International Classification:

H01S 5/00

US Classification:

372 46016, 372 4301, 372 46011, 372 46014, 372 64

Abstract:

A separate-confinement heterostructure, edge-emitting semiconductor laser having a wide emitter width has elongated spaced apart intermixed and disordered zones extending through and alongside the emitter parallel to the emission direction of the emitter. The intermixed zones inhibit lasing of high order modes. This limits the slow axis divergence of a beam emitted by the laser.
