摘要： A laser welding head rotates for welding a sleeve within a tube by fusing the interface between the sleeve and tube with a laser beam uses a focusing lens for focusing a laser beam transmitted through a housing which is inserted inside of the sleeve; a welding mirror directs the focused beam out of the housing and into contact with the sleeve, and is maintained a predetermined distance from the inside surface of the sleeve. Shield gas is supplied to the weld area and passes about the periphery of the focusing lens for cooling the focusing lens and the welding mirror. A recessed aperture is provided within the discharge outlet to prevent molten material from the weld site from splattering into the housing and onto the mirror or lens. Multiple discrete weld paths or continuous overlapping helical weld paths at each end of the sleeve are preferred. The laser delivers 500 to 700 watts to the weld area, and causes a fusion width of at least .1125 mm and penetrates the tube to a depth of about 6 mm.

摘要： A laser welding system in which a high power laser (72) produces the laser beam (80) for delivery to a weld site (60). A transmitter (74) is optically coupled to the laser (72) and directs the laser beam (80) to a spatially separated receiver (76). The receiver (76) has an input alignable for receiving the directed laser beam (80) and includes optics for delivering the laser beam (80) to the weld site (60). A pair of directable beam deflectors (90, 92, 100, 102) are employed for aligning the transmitter (74) and the receiver (76). A pair of steering deflectors (82, 84) introduce the laser beam (80) into the transmitter (74). A selectable mounting (164) allows the laser (72) to be secured at various orientations relative to the steering mirrors (82, 84) and the weld site (60). The transmitter (74) and the receiver (76) each has a detector (130, 134) positioned for receiving an alignment laser beam (122) at a point which indicates alignment.

摘要： A system for aligning a high-power laser apparatus to transmit a high-power beam along an optimum beam path to an adjustable remote beam receiver and for aligning the beam receiver for optimum reception of the high-power beam. A low-power visible laser is directed along the same path as to be followed by the high-power laser and, a video camera is used for rough alignment. A pellicle, a partially reflecting mirror, and three low-power beam detectors are used with the low-power laser to align the beam transmitter with the beam receiver. An annular beam detector mounted near the beam transmitter and a second beam detector mounted near the beam receiver form part of the alignment checking system. A beam intensity reducer reduces the intensity of the high-power beam for use in alignment, since prolonged direct contact by a full-power beam with the detectors would damage the detectors. A method for aligning the laser beam transmitter and receiver is also described.

摘要： A method for defining an array of light-emitting pixels in a thin film electroluminescent edge emitter structure includes the steps of moving the structure in proximity to a stationary first laser source as the first laser source is operated to generate a plurality of first laser pulses. The plurality of first laser pulses are focused into "lines" of light energy that strike the structure at a plurality of spaced apart locations in succession to ablate a predetermined number of layers of the structure. This ablation process forms a plurality of spaced apart channels in the structure. The portions of the structure remaining between each pair of adjacent channels define an array of pixels in the structure. The structure having the pixels formed therein is moved in proximity to a second laser source. The second laser source is movable in a selected direction substantially perpendicular to the direction of movement of the structure. The second laser source provides a second laser beam that is focused to a "point" of light energy which strikes the end portion of each pixel at an area inward of the pixel edge surface to ablate a predetermined number of layers at each pixel end portion. The movement of the second laser beam is controlled relative to the movement of the structure to correspondingly control the amount of material ablated inward of the edge surface of each pixel to remove the pixel edge surface and form a new pixel edge surface shaped to a preselected contour.

摘要： A detector for aligning a laser beam has been provided. The detector includes an insulative substrate (16), and a thermally conductive planar face (S) attached to the substrate. The face is divided into thermally isolated sectors (12), each sector having the same shape and area. A corresponding thermal sensitive device (26) is provided for each sector. Each sector is in thermal contact with a corresponding one of the thermal sensitive devices, and each thermal sensitive device produces a response proportional to the amount of laser energy impinging thereon to thereby provide indication of the misalignment of the laser beam relative to the transport path.
