A laser marker has: a controller configured to oscillate a laser beam; and a head configured to scan a machining surface of a machining target with the laser light. The controller is configured to transmit, to the image processing apparatus, a command for instructing the image processing apparatus to perform a predetermined scene, when the controller is set to cause the image processing apparatus to perform the scene. When the command is received, the image processing apparatus is configured to calculate a deviation amount of the machining target relative to a reference position using image data of an image of the machining target captured by the marker head and to notify the deviation amount to the controller. The controller is configured to correct a position to be scanned with the laser beam based on the deviation amount and then cause the marker head to perform the scanning.

For material processing of a material, which is in particular for a laser beam to a large extent transparent, asymmetric shaped modifications are created transverse to the propagation direction of the laser beam. Thereby, the laser beam is shaped for forming an elongated focus zone in the material, wherein the focus zone is such that it includes at least one intensity maximum, which is transverse flattened in a flattening direction, or a transverse and/or axial sequence of asymmetric intensity maxima, which are flattened in a sequence direction. After positioning the focus zone in the material, a modification is created and the material and the focus zone are moved relative to each other in the or across to the flattening direction or in the or across to the sequence direction for forming a crack along an induced preferred direction.

A method for marking, at the outlet of a forming machine using a laser beam, a marking area on hot glass containers comprises determining the longitudinal and transverse positions of the marking area of each container by positioning a first optical axis of a first light sensor and a second optical axis of a second light sensor in a non-parallel manner to each other, in a detection plane parallel to the conveying plane of the containers, detecting the instant of intersection or disengagement, by a container, of the first optical axis and the instant of intersection or disengagement, by a container, of the second optical axis, and calculating said transverse and longitudinal positions from these instants and in consideration of a known or constant speed of translation of the containers. The method can determine the marking instant for each container running past the laser apparatus.
