    Abstract: A laser alignment system is used to align an output fiber with a fiber laser, for example, when coupling a feeding fiber to a process fiber using a beam coupler or switch. The alignment system includes a laser alignment apparatus that is coupled at a first end to the output fiber and at a second end to a beam dump / power meter. The alignment apparatus defines a light passage and a light capture chamber along the light passage. When light is not aligned into the core of the output fiber, at least a portion of the light passing out of the output fiber will be captured by the light capture chamber and detected by a photodetector in optical communication with the light capture chamber. By monitoring the readings of the photodetector, the output fiber may be properly aligned with the laser light from the fiber laser.

    Abstract: A laser emitter (36) emits a laser beam (37) through optics (38) that focus the beam, and a beam deflection device (40) redirects the beam. An elongated probe (30) receives the beam at a proximal end (50) and has a remote mirror (24) that reflects the beam toward a hidden surface (32) to be processed by scanning of the beam. A programmable controller (54) controls focusing and deflection of the beam to move the focal point and spot of incidence (39) in three dimensions, causing the spot to traverse the hidden surface. The probe may optionally have translation (42) and rotation (44) actuators and a remote mirror pivot actuator (58) controlled by the controller. The probe may be L-shaped (30A, 30B) to reach around an intervening structure (27). An autofocus mechanism (67) may be provided to focus the beam during scanning or verify focus profiles before scanning.

    Abstract: Systems and methods for laser scribing provide extended depth affectation into a substrate or workpiece by focusing a laser beam such that the beam passes into the workpiece using a waveguide, self-focusing effect to cause internal crystal damage along a channel extending into the workpiece. Different optical effects may be used to facilitate the waveguide, self-focusing effect, such as multi-photon absorption in the material of the workpiece, transparency of the material of the workpiece, and aberrations of the focused laser. The laser beam may have a wavelength, pulse duration, and pulse energy, for example, to provide transmission through the material and multi-photon absorption in the material. An aberrated, focused laser beam may also be used to provide a longitudinal spherical aberration range sufficient to extend the effective depth of field (DOF) into the workpiece.
