摘要： A method for processing a workpiece includes the steps of arranging the workpiece in a work space and guiding an OCT measurement beam of an optical coherence tomograph using a processing head so as to scan the workpiece, wherein the pose of the processing head in the work space and also the pose of the OCT measurement beam relative to the processing head are known. Distance measurement values of the optical coherence tomograph are determined during the scanning, which are used to determine at least one of the pose of the workpiece in the workspace, the presence of a workpiece in the workspace, the identity of the workpiece in the workspace, and the presence of a processing feature of the workpiece that was carried out on the workpiece in a previous processing step.

摘要： A laser system is configured for providing a laser line (L) in a working plane (WP) for line illumination of an object. The laser line (L) extends in a first direction (x) over a significant length and in a second direction (y) over a small extent. The laser system includes a laser source for providing a laser beam as basis for an elongated input laser beam propagating along a propagation direction (z), and a homogenization and focusing unit for homogenizing the elongated laser beam to form the laser line (L). The laser system is, for example, suitable for providing a laser line (L) that can be stitched to another laser line (L′) of another laser system.

摘要： A device for transporting pulsed laser radiation includes a pulse duration setting device configured for setting a transport pulse duration of the pulsed laser radiation. the device further includes a hollow core optical fiber having a hollow core surrounded by a material. The hollow core optical fiber is configured to be operated with beam path parameter values that are present at the first fiber end and lie in a target tolerance range. The device further includes a fiber input coupling device configured to couple the pulsed laser radiation into the hollow core optical fiber with the beam path parameter values that lie in the target tolerance range. the transport pulse duration is set so that input coupling of the pulsed laser radiation into the hollow core is provided for all of the beam path parameter values in the target tolerance range.

摘要： A workpiece processing machine includes a separation device for dividing an operating space into a processing region and at least one additional operating region, a laser processing head configured to process the workpiece, and a rotary workpiece changer having a rotatable workpiece support for transporting the workpiece between the processing region and the at least one additional operating region by an opening. The rotatable workpiece support has a protection wall configured to shield the at least one additional operating region with respect to the processing region. The separation device has a protection element movable between a processing position and a transport position and configured to be in abutment with the protection wall in the processing position to close the opening and spaced apart from the protection wall in the transport position. A spacing between the processing position and the transport position is adjustable based on a dimension of the workpiece.

摘要： A laser pulse generator includes a pulse shape generation device and a clock unit. The generation device includes a pulse shape repository, a digital-to-analog converter (DAC), a first terminal for connecting a start signal line, a second terminal for connecting a clock signal line, and a third terminal for connecting a pulse line. The first and second terminals are connected to the pulse shape repository and the DAC such that when a predefined start signal is present, data is transferred from the pulse shape repository to the DAC and converted by the DAC into an output pulse, for example, at a rate of a clock signal. The output pulse is supplied at the third terminal for actuating a driver of a laser diode. The clock unit is connected to the second terminal via the clock signal line and includes a reset terminal connected to the start signal line.

摘要： An apparatus for coupling out radiation from an optical fiber, includes a housing, and a stop having a stop opening for delimiting an output coupling angle of radiation that is coupled out of an output end of the optical fiber to a maximum output coupling angle with respect to a central axis of the stop opening, wherein the stop is arranged in the housing. The stop has a stop body made from a transparent material, the stop body has a first total internal reflection face for reflecting radiation that is coupled out of the output end of the optical fiber with greater output coupling angles than the maximum output coupling angle, and the stop body has a second total internal reflection face for reflecting radiation that propagates opposite to the radiation coupled out of the output end and is reflected back by a workpiece.

摘要： An optical element holding device adjusts an optical element about a first and second axis and includes a main support, and a first plate-shaped support mounted on the main support via a first flexure bearing. The first support can pivot about the first axis. A second support is mounted on the first support via a second flexure bearing and can pivot about the second axis and fasten to the optical element. A first and second actuating element are actuated from a same side of the optical element holding device. A transmission device connected to the first and the second supports transmits the second actuating element movement acting on the transmission device into a pivoting movement of the second support about the second axis. The pivoting positions of the first and second supports can be set by the actuating elements and the second axis is oriented substantially perpendicularly to the plate-shaped first support.
