Abstract: A method of applying a precompensation for shrinkage during a real-time assembly of an optical component. Prior to the real-time assembly, (a) the optical component is aligned to obtain a reference position (href); (b) pre-assembly laser beam data (reference beam size (?ref), reference beam position (pref), beam size (?), and beam position (p)) is plotted; (c) the optical component is aligned in one or more positions (h) and repeating step (b) for each position (h); (d) adhesive is applied to the base; (e) curing the adhesive; (f) test laser beam data (beam size (?cure) and beam position (pcure)) is plotted; (g) position of the optical component (hcure) is determined based on pre-assembly and test laser beam data; (h) a precompensation value (|href?hcure|) is calculated; and (i) the optical component is aligned at a height (|href?hcure|+href) before performing step (e) during the real-time assembly.

Abstract: A laser system includes a plurality of laser sources and a plurality of collimating lenses. The system further includes a focus lens configured to receive laser beams outputted from the plurality of collimating lenses and focus the laser beams to at least one focal point in the core region or in the outer cladding region of the optical fiber. The optical fiber includes a core region, an inner cladding region and an outer cladding region, the optical fiber configured to output a dual laser beam comprising a main beam generated from the core region and a ring beam generated from the outer cladding region, the ring beam surrounding the main beam. Each of the plurality of collimating lenses is individually arranged at a respective position so as to adjust a location of the focal point in one of the core region or the outer cladding region of the optical fiber.

Abstract: A laser marking tool for use with a CNC machine is disclosed. The laser marking tool includes a housing; a laser disposed within the housing; at least one sensor disposed within the housing and adapted to interpret a predetermined motion of the CNC machine as a command for the tool to perform a respective predetermined function; and a power source coupled to the laser. The at least one senor is an accelerometer and/or a gyroscope. The respective predetermined function comprises one or more of: powering the laser off/on, synchronizing the laser marking tool, and loading one of the patterns stored in a local memory.

Abstract: A wireless laser marking tool for use in a CNC machine is disclosed. The wireless laser marking tool includes a tool housing with top and bottom opposing ends, a beam delivery system between the ends, and an opening at the bottom end; a tool adapter connected to the top end of the housing for adapting the device to the CNC machine; a laser diode disposed in the beam delivery system; beam-shaping optics disposed in the beam delivery system to focus light emitted from the laser diode through the opening; electronic circuitry disposed in the beam delivery system and in electrical communication with the laser diode; a wireless communication device disposed in the beam delivery system and in electrical communication with the electronic circuitry; and a power source disposed in the beam delivery system and electrically connected to the electronic circuitry.
