US Patent:

6353315, Mar 5, 2002

Filed:

Aug 27, 1999

Appl. No.:

09/384939

Inventors:

Curtis Egan - Thornton CO
Steve McCarthy - Platteville CO
David Winters - Fremont CA

Assignee:

Maxtor Corporation - Longmont CO

International Classification:

G01R 3312

US Classification:

324212, 360 25, 360 31, 714718

Abstract:

A byte wide flaw scan interface is used to identify an characterize flaws in a disk medium. In one embodiment, the associated disk drive ( ) includes head electronics ( ) associated with a disk drive controller ( ) via an NRZ interface ( ). The NRZ interface ( ) is operative for transmitting flaw information for a particular disk address via 8 predefined bit lines. The bit lines have separate definitions for user data sector addresses and servo wedge addresses. By using this byte wide interface, media flaws of various types can be identified and characterized based on a single pass of the transducer head over the disk surface thereby shortening testing times.

International Classification:

G02F 1/35
G02F 1/39

Abstract:

Apparatus and methods for generating controllable, narrow-band radiation at short wavelengths, driven by two colors injected into a structured waveguide. The use of multicolor excitation with the structured waveguide allows the use of very small guided beam diameters, without damaging the waveguide. Reduced guided wave mode area combined with low intensities required to drive wave-mixing frequency conversion allow the use of very compact, high average power, moderate peak intensity femtosecond fiber laser technology to drive useful conversion efficiency of laser light into the deep-UV and vacuum-UV at MHz repetition rates.

Scott R Domingue - Boulder CO, US

International Classification:

G02F 1/35
H01S 3/00
G02F 1/39

Abstract:

An integrated, vertically stacked device includes a laser in an enclosure, a wavelength converter in an enclosure, a mechanical interface for attaching the enclosures and maintaining the laser and wavelength converter in the same plane, and apparatus for directing light from the laser to the wavelength converter within the footprint of the integrated device.

Appl. No.:

15/156320

Inventors:

- Boulder CO, US
Sterling Backus - Boulder CO, US
David Winters - Erie CO, US

International Classification:

H01S 3/067
H01S 3/094

Abstract:

A system for single pass amplification of dissipative soliton-like seed pulses of 1-20 ps to produce output pulses of 50-200 fs, without requiring a stretcher. Such an amplifier relies on the inherent chirp of the seed pulse out of the oscillator instead of pulse stretching.
