摘要： The disclosed laser system is configured with a laser source outputting light at a fundamental frequency. The output light is incident on a frequency converter operative to convert the fundamental frequency to a higher harmonic including at least one frequency converting stage. The frequency converter is based on a SrB 4 O 7 (SBO) or PbB 4 O 7 (PBO) nonlinear crystal configured with a plurality of domains. The domains have periodically alternating polarity of the crystal axis enabling a QPM use and formed with each with highly parallel walls which deviate from one another less than 1 micron over a 10 mm distance.

摘要： The present application relates to a laser welding head (10). The latter comprises movable mirrors (132, 34), which are used to perform welding operations, for example, with wobble patterns and/or seam finding/tracking and following. The movable mirrors (132, 134) provide a wobbling movement of one or more beams (118) within a relatively small field of view, for example, defined by a scan angle of 1-2°. The movable mirrors (132, 134) may be galvanometer mirrors that are controllable by a control system (160) including a galvo controller. The laser welding head (110) may also include a diffractive optical element to shape the beam or beams (118) being moved. The control system (160) may also be used to control the fiber laser (112), for example, in response to the position of the beams (118) elative to the workpiece (102) and/or a sensed condition in the welding head (110) such as a thermal condition proximate one of the mirrors (132, 134).
