    摘要： An optical waveguide laser, preferably a fiber laser, has unintentionally incorporated impurities disposed in the lasing medium which upconvert a portion of the lasing radiation to radiation of shorter wavelength, thereby introducing defects in the medium which result in increased absorption due to photodarkening. Suitable rare-earth co-dopants are intentionally incorporated during the manufacture of the fiber for effectively shunting the upconversion process. The lifetime of the fiber laser is thereby increased.

    摘要： Novel solid state gain mediums provide monolithic lasers with short cavity lengths and with the ability to efficiently lase in the lowest order TEM.sub.00 mode. Unoptimized optical power conversion efficiency of 35% has been achieved with the novel solid state gain mediums in monolithic lasers that have a cavity length as short as 0.5 mm. With proper values for the output mirror reflectivity and low loss host crystals, the optical power conversion efficiency is approximately 50%. Moreover, when in optical contact with a frequency doubling optically non linear crystal, the novel solid state gain mediums in the monolithic lasers can produce coherent visible light.

    摘要： An up converting method and apparatus includes a crystalline structure responsive to light emitted from pump light for producing visible and/or ultraviolet light therefrom which is of a shorter wavelength than the pump light. This crystalline structure comprises a composition containing active ions of trivalent rare earth elements and a host material of either anhydrous rare earth halides or rare earth oxysulfides. This crystalline structure is represented by the atomic formula M.sub.(1-x) R.sub.x Z.sub.3 or M.sub.2(1-x) R.sub.2x O.sub.2 S where M comprises at least one rare earth element selected from the group comprising cerium, gadolinium, yttrium, lanthanum, and mixtures thereof, R is a dopant selected from the group comprising neodymium, thulium, erbium, holmium, samarium, and mixtures thereof, x is a value in the range from 0.005 to 1.0, and Z is a halogen selected from the group comprising chlorine, bromine, and iodine. When optically pumped, the crystalline structure produces visible and/or ultraviolet light by either a direct or indirect two step up conversion process. An electronic printing apparatus can also use the up converting crystalline structures to expose photosensitive media in the manner of this invention.

    摘要： A method and apparatuses are provided for data collection from network elements in a network. A collector sends a data request to one of the network elements. The collector determines whether a condition exists regarding the network element. When the collector determines that the condition exists, the collector stops the data collection from the network element without affecting the data collection by the collector from other network elements, the data collection remains stopped until the collector is notified that the condition no longer exists, and the collector sends a message to the validator to inform the validator of the condition. In another aspect, a validator is informed of a configuration change of one of a group of network elements. The validator requests at least a portion of configuration information of the network element, determines optimum configuration parameters for data collection, and sends the optimum configuration parameters to a collector.

    摘要： A fabrication technique is described for making various devices in which a certain type of glass is used as a surface protection layer. The glass layers are formed by particle bombardment (generally sputtering or E-beam) of a glass target. Devices with such surface layers are also described. Such glass layers are highly advantageous as encapsulating layers, diffusion barrier layers, etc., particularly for optical type devices and certain semiconductor devices. Particularly important is the preparation procedure for the glass target used in the bombardment process. The glass layers are moisture stable, act as excellent barriers against diffusion, and are usable up to quite high temperatures (i.e., in diffusion doping procedures) without cracking or peeling. The glass layers also provide long-term protection against atmosphere components including water vapor, oxygen, atmosphere pollution contaminants, etc., and can be removed by standard etching techniques.

    摘要： The invention is a process for putting down coatings of aluminum oxide on optical surfaces using electron-beam deposition in an oxygen-enriched atmosphere. Particularly good results are obtained when oxygen is flowed over or directed at the surface to be coated. Such coatings have extremely low losses compared to many conventional optical coatings and are particularly useful for anti-reflection coatings on various devices. In particular, for optical devices with indium phosphide surfaces operating at wavelengths near 1.3 .mu.m, the optical properties of aluminum oxide coatings are near optimum for anti-reflection coatings and the thermal expansion characteristics are a close match to those of indium phosphide.
