摘要： A process and device for forming and guiding the radiation field or one or several solid and/or semiconductor lasers, in particular the radiation field of an array or field arrangement of one or several solid and/or semiconductor lasers, comprise radiation transformation optics with refractive elements that generate a defined radiation field. The device is characterized in that the radiation field (4) is subdivided into at least two radiation fractions according to predetermined data. Each radiation fraction enters an associated refractive element (6, 15, 19, 21, 23, 24) with predetermined co-ordinates. Each refractive element (6, 15, 19, 21, 23, 24) refracts the corresponding radiation fraction on at least one of its surfaces (7) so that the radiation fractions leave the refractive elements (6, 15, 19, 21, 23, 24) with output co-ordinates and/or propagation directions modified in relation to each other.

摘要： An apparatus for maintaining an electromagnetic beam, namely a laser beam, aimed at a particular point in space and aligned with a unique propagation path. The apparatus includes one or more adjustable beam steerers located in the propagation path, and first and second spaced apart beam position detectors arranged in the beam path. The beam steerer(s) are preferably adjustable along at least two orthogonal axes of rotation for controlling the propagation direction of the beam. Error signals from the position sensors are fed into a beam steerer controller connected to the beam steerer(s) for electro-mechanically adjusting the beam steerer. The method of the invention involves fixing the propagation path on an angularly adjustable beam steering surface so that the propagation path at a different unique point in space, such as a target, can be controlled by adjusting the angular orientation of that beam steerer.

摘要： A laser apparatus for medical treatment use in which a laser beam is irradiated on a portion of a human body to be treated comprises a laser beam generation unit for generating a laser beam of giant pulse, a laser beam guide member having one end through which the laser beam from the laser beam generation unit is guided, and a hand piece attached to another end of the laser beam guide member and irradiating the laser beam to the portion to be treated. A beam converging point is formed within a laser beam propagating path formed in at least one of the light guiding means and the hand piece and a stay of air is prevented from a predetermined region in the laser beam propagating path including at least the beam converging point at which the air stays. The predetermined region is positioned within the hand piece or the laser beam guide member. The air stay is prevented by means of producing a vacuum state, gas seal state or air flow state in the predetermined region.

摘要： A laser beam condensing device which can be manufactured at low cost by using reflecting mirrors which can be machined at low cost. The device is capable of condensing a laser beam to a high energy density while eliminating any optical path difference, even if the optical axis of the incident beam strays. This device includes a first and a second reflecting mirror. An incident laser beam is deflected by these mirrors in the same direction. One of the two mirrors is a toroidal mirror, while the other is a spherical, cylindrical or toroidal reflecting mirror. The mirror surfaces of the two reflecting mirrors are machined so that the second reflecting mirror can cancel out any wave front aberrations of the laser beam reflected by the first reflecting mirror.

摘要： An optical scanning apparatus includes a semiconductor laser, a polygonal mirror as a deflector for scanning a light beam from the laser, a photosensitive drum for forming an electrostatic latent image, a converging lens for converging the light beam from the laser onto the photosensitive drum, and a reflection mirror located between the deflector and the photosensitive drum. The reflection mirror is adapted to reflect the light beam so that a light beam reflected by the reflection mirror is used to read a source document placed at a position that is the conjugate of the position of the photosensitive drum surface with respect to the converging device. Inside the casing of the semiconductor laser are a beam splitter for light path separation and a photosensor. The apparatus has an image reader section and a laser printer section, which share a common optical system, thus providing a compact design and cost reduction and also equalizes the accuracy of image reading and printing.

摘要： An illumination apparatus has at least one of a luminous flux angle adjustment means and a luminous flux translation means. Due to these luminous flux angle adjustment means and luminous flux translation means, the inclination and positional deviation of a luminous flux can be corrected with a high accuracy without finely adjusting the position of the light source. Accordingly, when this illumination apparatus is incorporated in a projection exposure apparatus, change in exposure light quantity and fluctuation in illuminance can be suppressed so as to stably effect exposure.

摘要： System and method for laser welding an inner surface of a tubular member, which tubular member may be a repair sleeve disposed in a nuclear heat exchanger heat transfer tube. The system includes a laser for generating high intensity laser light sufficient to fuse the sleeve to the inside diameter of the heat exchanger tube, the tube being of the type typically found in nuclear heat exchangers. A fiber-optic cable is optically coupled to the laser for conducting the laser light therethrough. The fiber-optic cable has a predetermined configuration to homogenize the laser light so that the laser light obtains the desired spatial coherency as the light is emitted from the fiber-optic cable. A mirror is optically coupled to the fiber-optic cable so as to receive the homogenized light beam emitted from the fiber-optic cable. The mirror is also optically coupled to the inner diameter of the sleeve for reflecting the homogenized light beam onto the inner diameter of the sleeve to weld or fuse the sleeve to of the tube. In this manner, the sleeve is welded to the inside diameter of the tube to sleeve the tube.

摘要： A polarization insensitive fiber laser. A pair of 45 degree Faraday rotators are positioned on either end of the fiber gain source. The resulting laser is insensitive to external perturbations with respect to known entrance and exit polarization states of the laser light. Modelocking, both passive and active, is possible.

摘要： There is disclosed a device for emitting light diverging along an imaginary plane. This device includes a light source, a collimating lens, and a cylindrical optical element which are mounted within a casing. A reflecting surface, inclined with respect to an axis of the optical element, and a cylindrical surface extending along the axis of the optical element are formed on one end portion of the optical element disposed near one end portion of the casing. That portion of the optical element including this cylindrical surface serves as a cylindrical lens portion. The beam from the collimating lens advances along the axis of the optical element, and is reflected by the reflection surface to be directed toward the cylindrical lens portion. This reflected beam is converted by the cylindrical lens portion into a beam diverging along the imaginary plane disposed generally perpendicular to the axis of the optical element, and is emitted from the casing.
