Abstract: The dynamic energy and spot size adjustment method for laser processing with an optical microscope is applied to a laser processing machine which includes a console, a calculation module, a laser source, a beam adjustment unit, a galvanometer scanner, a light sensor, a vision module, an F-theta lens, a beam splitter, and an objective lens. The laser source generates a laser beam passing through the beam adjustment unit to form a laser processing beam which further passes through the galvanometer scanner, the F-theta lens, the beam splitter, and the objective lens to focus on a working plane. The beam splitter respectively guides parts of the laser processing beam to the vision module and the light sensor. The vision module and the light sensor cooperate with the calculation module to identify/measure and record the energy and spot size of the laser processing beam as dynamic adjustment references during laser processing.

Abstract: An optical fiber transmission system with a laser beam splitting and combining device includes a laser beam splitting and combining device receiving a laser beam from a laser device and projecting the laser beam onto a target through an objective lens. The laser beam splitting and combining device has a beam splitter, two transmitters, two receivers and a beam combiner. When the beam splitter divides the received laser beam and transmits the divided laser beams to the transmitters, the transmitters transmit the divided laser beams to the receivers through two optical fibers. The receivers send the divided laser beams to the beam combiner for the beam combiner to combine the divided laser beams into an output laser beam projected on the target through the objective lens. Given the optical transmission path of the laser beam splitting and combining device, the laser transmission distance can be extended.
