    Abstract: A laser incorporating a laser medium disposed within a laser cavity and a pumping arrangement for selectively applying excitation energy to said laser medium. The laser medium contains upconverting material of the type which allows for the exchange of energy between electrons of the lasing ions at a given energy state below the meta-stable initial lasing state so that some of said exchanging electrons are upconverted to energy states at or above the meta-stable initial lasing state. The pumping arrangement applied energy of suitable wavelength and intensity for elevating electrons from energy levels below the given state to that state in sufficient numbers to support substantial upconversion and the resulting lasing.

    Abstract: Apparatus for measuring the numerical aperture of an optical fiber in the infrared region. The optical fiber (8) is appropriately mounted in accordance with conventional testing standards. Infrared energy is transmitted through the optical fiber (8). At a predetermined distance from the end of the optical fiber, a conversion screen (10) can be provided for transforming the emitted infrared energy into a lesser wavelength of energy. The energy distribution can be recorded with a detector compatible with the lesser wavelength energy whereby the numerical aperture can be computed from the recorded data.

    Abstract: An improved curing oven is disclosed. The present invention (10) provides an improved curing oven which cures materials with electromagnetic radiation in the ultraviolet region. The invention consists of a surface (12) lined with a layer of material (14) effective to radiate ultraviolet radiation in response to the application of infrared radiation. In a specific illustrative implementation, the invention (10) includes a second surface (18) overlying the first surface (12) providing a passageway therebetween. The oven temperature is set and maintained by a conventional temperature controller (20). Tne temperature controller (20) measures the oven temperature and controls a valve (22) which adjusts the gas pressure from a gas supply (24) to a set of oven burners (26). Air is supplied through inlet ports (28) included in the second surface (18).

    Abstract: The method of producing at least quasi-continuous lasing operation between initial and terminal lasing states comprising the steps of selecting a laser medium and cavity configuration (lasing frequency) with the laser medium containing upconverting material which provides for the exchange of energy between sufficient number of electrons at the terminal lasing state (manifold) so as to maintain population inversion between the initial and terminal lasing states during the lasing operation; and applying excitation energy of a suitable amount to the laser medium during at least a quasi-continuous time period.

    Abstract: Appareil pour mesurer l'ouverture numérique d'une fibre optique dans la région infrarouge. La fibre optique est montée de manière appropriée conformément aux normes d'essai classiques. On transmet de l'énergie infrarouge à travers les fibres optiques. A une distance prédéterminée de l'extrémité de la fibre optique, on peut disposer un écran de conversion pour transformer l'énergie infrarouge émise en une énergie de longueur d'onde inférieure. On peut enregistrer la distribution d'énergie à l'aide d'un détecteur compatible avec l'énergie de longueur d'onde inférieure, l'ouverture numérique pouvant être calculée à partir des données enregistrées.

    Abstract: Le laser décrit comprend un milieu laser disposé dans une cavité à laser et un agencement de pompage pour appliquer sélectivement une énergie excitatrice au milieu laser. Le milieu laser contient un matériau de conversion incrémentielle du type permettant l'échange d'énergie entre des électrons des ions à effet laser à un état d'énergie donné inférieur à l'état laser initial métastable de sorte que certains des électrons d'échange sont convertis de manière incrémentielle à des états d'énergie égaux ou supérieurs à l'état laser initial métastable. L'agencement de pompage applique un énergie de longueur d'onde et d'intensité appropriées pour élever des électrons depuis des niveaux d'énergie inférieurs à l'état donné jusqu'à cet état en question en nombres suffisants pour supporter une conversion incrémentielle substantielle ainsi que l'effet laser résultant.
