Abstract

An air-cooled THS of ceramics solder-mounts a distributed array of LDs and the ICs for an advanced electronics. This high power, compact, hermetic and self-cooled hybrid engine hosts also the coupling optics behind a window. Inside, many well spaced Laser Diodes / LDs emit a regular field of rays; next, a mating array of optical elements collectively reshapes each beam. After crossing the window, a large aspheric mirror collects and focuses the beams. Its reasonably tight focus and consistent powers can weld directly many materials or perform other industrial tasks. The system can also integrate more CCD and OE sensors to properly automate each welding etc sequence. On current coolers, the LDs face substantial optical limits, a complex assembly and many practical restrictions. The THS handles large powers avoiding water; a standard Pick and Placer can assemble nearly raw LD dices; a larger spacing gets around the optical constraint and many LDs can work concurrently, to behave as a true laser.
