    摘要: A two-dimensional LD (laser diode) array light-emitting device constituted by stacking light-emitting units each having a LD bar and a cooling assembly for cooling the LD bar with a simplified electrical connection structure to reduce manufacturing cost. The cooling assembly is electrically connected with one electrode of the LD bar through the die spacer so that a part of the cooling assembly serves as one electrode of the light-emitting unit. The other electrode of the LD bar is electrically connected with a webbed extending section of a conductive layer of a TAB (tape-automated bonding) sheet so that the conductive layer serves as the other electrode of the light-emitting unit. A space between the adjacent cooling assemblies for arranging the LD bar is adjusted by the spacer sheet intervened between the TAB sheet and the cooling assembly.

    摘要: A cooling device for a semiconductor component which increases mechanical strength thereof and reduces a pressure loss of coolant. Plate members constituting the cooling device are formed with flow passages such as coolant supply and discharge openings, grooves divided by ridges, and through portions separated by projections or partitions. The ridges, projections, and partitions are joined to a adjacent plate member to increase the joining strength, which is further increased by forming the ridges, projections, and partitions of different plate members at the same positions. In the case of laminating the plate members having surfaces formed with solder layers, a number of minute vacant spaces are formed in those joining faces of the plate members which are not formed with passages, etc., and solder filets are formed over the entire joining faces to increase the joining strength. The grooves and through portions can be formed by chemical etching together with outer shapes of the plate members. A plurality of plate members can be fabricated from a single sheet material at a time.

    摘要: A cooling device suitable for cooling a laser diode bar constituting a surface illuminating device as a light source for exciting a laser medium of a solid-state laser oscillator of high power. The cooling device is capable of flowing coolant at sufficient flow rate by reducing the pressure loss in the flow passage of the coolant in the device, to realize a light source device of small thickness with high cooling capability and high reliability. The cooling device comprises a first plate member, one or more second plate member and a third plate member to be joined together to form a laminated body. The second plate member has grooved paths formed on both surfaces thereof and having depths greater than a half of thickness of the plate member, and also opened paths for communicating grooved paths formed on the first plate member and the third plate member. The pressure loss in the flow passage of coolant is reduced by increasing a sectional area of the flow passage by the grooved paths and the opened path of the second plate member without lowering mechanical strength of the device and without increasing a manufacturing cost of the device.

    摘要: A high-power laser unit capable of accurately correcting laser output from low to rated outputs, even when the laser unit has a laser power monitor which may be affected by environmental factors inside or outside the laser unit, by effectively reducing environmental factors. The laser unit has a laser power monitor for measuring laser output, and a laser controller for correcting the laser output by correcting an amount of excitation energy to a laser power supply so that a measurement value coincides with a laser output command value. The laser unit has a laser output commanding part for generating a laser output command. When it is not necessary to correct the laser output command, the laser output command is converted into an excitation energy command value and sent to the power supply. Otherwise, an output correcting part of the laser controller corrects the laser output command.
