Abstract: A welding mode determination device that determines a welding mode when laser beam welding is performed includes an obtaining unit that obtains an image in an infrared wavelength region and an image in a short wavelength region of visible light from a laser irradiation area and its vicinity. An extraction unit extracts a light emitting image from the image in the infrared wavelength region and a light emitting image from the image in the short wavelength region of visible light. A determination unit compares the light emitting image of the image in the infrared wavelength region and the light emitting image of the image in the short wavelength region of visible light and determines the welding mode when the laser beam welding is performed based on a comparison result.

Abstract: A laser processing apparatus includes a support part, a light source, a spatial light modulator, a converging part, a moving part, and a control part. When a relative movement direction of a first converging point of first processing light and a second converging point of second processing light is set to an X direction, and a direction perpendicular to a Z direction and the X direction is set to a Y direction, the control part controls the spatial light modulator and the moving part such that the first converging point and the second converging point relatively move along a first line and a second line in the object in a state where the first converging point and the second converging point are shifted from each other in each of the X direction and the Y direction.

Abstract: A method of removing contaminants from a surface of a gas turbine engine component protected by a diffusion coating that comprises an additive layer on the surface of the component and a diffusion zone in the surface of the component. The method includes subjecting the surface containing contaminants to laser beam pulses to remove contaminants from the component such that contaminants on the surface of the component are removed without damaging or removing the diffusion zone of the diffusion coating. Methods for controlled removal of at least a portion of a thickness of a diffusion coating from a coated superalloy component are also provided.

Abstract: Laser control systems and related methods for controlling arrays of lasers are disclosed. A laser control system may include a first controller configured to generate a trigger signal based on a position of a laser array, and a second controller configured to send a firing signal to one or more lasers of the laser array upon receiving the trigger signal. The one or more lasers may be selected based on a desired pattern of laser energy to be formed at a particular position of the laser array.

Abstract: Detectors are situated along a tilted optical axis to receive optical radiation from a work surface. Variations in the received optical power are used to estimate a work surface positional along a work surface axis. The received optical power can be emitted from the work surface and an estimated temperature of the work surface used to adjust the received optical power. One or two single element detectors or a linear detector can be used. A position of a focused spot produced from the received optical power at the linear detector can be used to assess work surface axial position.

Abstract: A method of processing by controlling one or more beam characteristics of an optical beam may include: launching the optical beam into a first length of fiber having a first refractive-index profile (RIP); coupling the optical beam from the first length of fiber into a second length of fiber having a second RIP and one or more confinement regions; modifying the one or more beam characteristics of the optical beam in the first length of fiber, in the second length of fiber, or in the first and second lengths of fiber; confining the modified one or more beam characteristics of the optical beam within the one or more confinement regions of the second length of fiber; and/or generating an output beam, having the modified one or more beam characteristics of the optical beam, from the second length of fiber. The first RIP may differ from the second RIP.
