摘要： Alignment of a laser apparatus is achieved by actively aligning components of the laser apparatus and then passively deriving an optical axis from that alignment. This passive derivation can be achieved by identifying features of an actively aligned optical element, deriving positional data for those features, and developing an optical axis from that positional data. The derivation of positional data may be performed over a particular coordinate system of an image taken of the feature, e.g., obtained by a vision system. The positional data and optical axis may be extrapolated out to a reference coordinate system for use in passively aligning other optical elements.

摘要： Known laser diode selections are limited to those designed for high power applications (high gain) or those designed for stable single mode operation in an external cavity (low gain). Exponential gain of laser diodes implemented according to embodiments of the present invention is improved (i.e., optimized) to provide both high output power and stability in an external cavity. This is accomplished by controlling the number of quantum wells, light confinement factor, and the transparency current of the laser diode.

摘要： An optical data storage system and method comprising a photopolymer medium having generally a polymerizable monomer, an active binder, a first, hologram recording polymerization initiator, and a second, data writing polymerization initiator. The monomer is preferably a cationic ring-opening monomer. The hologram recording polymerization initiator preferably comprises a sensitizer and photoacid generator which initiate a first polymerization in the medium which defines a format hologram. The format hologram recording is carried out via interference of a signal and reference beam, with the sensitizer being specific for the wavelength(s) of the signal and reference beams. The hologram recording polymerization is only partial and does not consume all of the monomer present in the photopolymer medium. A second stage, a data writing polymerization initiator, specific to a data writing beam, locally advances polymerization at selected data storage locations to alter the previously recorded format hologram, resulting in optical data storage as localized alterations in the format hologram.
