摘要： A laser marking system for marking a product includes a marking head having an electromagnetic radiation steering mechanism configured to steer electromagnetic radiation to address a specific location within a two-dimensional field of view. The electromagnetic radiation steering mechanism comprises a first optical element having an associated first actuator configured to rotate the first optical element about a first rotational axis to change a first coordinate of a first steering axis in the two-dimensional field of view and a second optical element having an associated second actuator configured to rotate the second optical element about a second rotational axis to change a second coordinate of a second steering axis in the two-dimensional field of view. The electromagnetic radiation steering mechanism comprises an electromagnetic radiation manipulator configured to introduce a difference between a first angle and a second angle (defined between the first and second rotational and steering (respectively) axes).

摘要： Embodiments of the inventive concept provide a substrate treating apparatus and a substrate treating method for not letting an irradiation region of a laser deviate from a target region, even if a shaking angle of a chemical deviates from an allowable range due to a vibration or an airflow. The inventive concept provides a substrate treating apparatus. The substrate treating apparatus includes: a substrate support unit configured to support a substrate having a chemical coated thereon; a laser generation unit configured to irradiate a laser to the substrate; and a light-transmitter positioned along a path at which the laser is irradiated.

摘要： A laser machining device having a surface plate upon which a material to be machined is placed, a rail, a saddle, a garter, a horizontal carriage, and a laser nozzle. On it is attached: a machining trolley that causes the saddle to travel along rail, causes the horizontal carriage to travel horizontally along garter, irradiates laser light from laser nozzle towards a material to be machined, and cuts or welds the material. A cover is provided that covers substantially the entire surface of machining trolley and has an upper surface cover, a laser nozzle-side cover, a garter-side cover, and a side surface body. On a lower end side of the laser nozzle-side cover and the garter-side cover, there is a flexible light-blocking member for preventing laser light from leaking from a gap between the lower end section and the upper surface of the surface plate.

摘要： Devices and methods for optical-fiber processing for connector applications are disclosed, wherein the devices and methods utilize a quantum cascade laser operated under select processing parameters to carry out end face polishing. The method includes supporting the optical fiber in a ferrule so that a bare end section of the fiber protrudes from an end of the ferrule by a protrusion distance. The method then includes irradiating the end face with light from the quantum cascade laser to polish the end face. The quantum cascade laser can also be used to form a bump in a central portion of the end face, wherein the bump facilitates physical contact between respective end faces of connected optical fibers.

摘要： An object is irradiated with a laser light modulated by a reflection type spatial light modulator such that aberration of the laser light converged inside the object becomes a predetermined aberration or less. Therefore, aberration of the laser light generated at a position on which a converging point of the laser light is located is made as small as possible, to enhance the energy density of the laser light at that position, which makes it possible to form a modified region with a high function as a starting point for cutting. In addition, because the reflection type spatial light modulator is used, it is possible to improve the utilization efficiency of the laser light as compared with a transmissive type spatial light modulator.

摘要： A processing system for micro processing. The processing system comprises a laser configured to generate a laser beam for performing laser processing within a preparation chamber. The processing system further comprises a transmission window, configured such that the laser beam enters into the preparation chamber through the transmission window. The processing system further comprises a fastening flange for fixing the transmission window relative to the preparation chamber, and a laser shield configured to provide, in a first arrangement of the laser shield, glare protection from a passage of the laser beam from a laser beam housing to the preparation chamber. The laser shield is movably mounted for movement between the first arrangement and a second arrangement of the laser shield, wherein in the second arrangement, at least one of the transmission window and the fastening flange is separable from the processing system.
