Filed:

Jan 16, 2001

Appl. No.:

09/765089

Inventors:

Roy D. Mead - Lynnwood WA
Jeffrey W. Pierce - Monroe WA

Assignee:

Aculight Corporation - Bothell WA

International Classification:

B23K 2600

US Classification:

2191217, 21912171, 21912172, 21912161, 21912168, 372 10, 372 12

Abstract:

A laser via drilling system, and a method of use thereof, is provided. The apparatus uses two or more laser systems to achieve processing parameter flexibility. The output beams from the independently controlled laser systems are combined using a beam splitter that combines the beams into single or multiple processing beams. The operational flexibility of the system can be further enhanced through the use of multiple EO modulators and a polarization sensitive beam splitter.

International Classification:

G06T 1500

US Classification:

345419

Abstract:

A method and a computer-readable medium are provided for generating an interface in a personal computer system. The method includes is playing a primary view of a three-dimensional environment from the egocentric perspective of a virtual person in the environment. A glancing function is then performed, which provides animated movement of the virtual persons head to reveal a three-dimensional tool space that is normally hidden from view. In one embodiment, the three-dimensional tool space moves with or is linked to the virtual persons body so that it travels through the environment with the virtual persons body. In other embodiments, the tool space is associated with an object in the three-dimensional environment.

US Classification:

Abstract:

A method and apparatus for fabricating extremely robust opto-electronic devices on a monolithic support structure is provided. Incorporated into the support structure are registration structures that are used to quickly and accurately align the various components associated with the device, typically eliminating the need for manual component alignment. The registration structures are fabricated using conventional lithographic techniques, offering alignment accuracy of a micrometer or less. Utilizing the registration structures, a gain module is fabricated that is comprised of at least a pump laser, an optical element, and a solid state gain medium. The pump laser is preferably a semiconductor diode laser that pumps the edge of the gain medium, thus eliminating many of the difficulties that arise from end pumping the medium. The optical element, interposed between the pump laser and the gain medium, collimates and/or focuses the emissions from the pump laser onto the laser medium in such a manner as to optimize the efficiency of the module. The gain module may include several pump lasers, thus increasing the achieved output power.
