Abstract: A fiber combiner includes a capillary and a plurality of input fibers disposed within the capillary. A first portion of the capillary has a first non-zero slope profile along a first portion of an output end of the fiber combiner. A second portion of the capillary has a second non-zero slope profile along a second portion of the output end of the fiber combiner. The second non-zero slope profile is different than the first non-zero slope profile.

Abstract: An optical fiber includes a core configured to transmit laser light and a cladding that surrounds the core. In some implementations, an outer surface region of the cladding is tapered or comprises a plurality of notches. The outer surface region of the cladding is configured to cause an aiming beam that falls incident upon the outer surface region of the cladding at a first incidence angle to fall incident upon an outer surface region of the core at a second incidence angle to allow the aiming beam to couple into the core.

Abstract: A system may perform an uptapering process to cause a signal fiber to have a fiber core with a first uptapered thickness profile and a fiber cladding with a second uptapered thickness profile. The system may perform, after performing the uptapering process, an uptapering removal process to cause the fiber cladding of the signal fiber to not have the second uptapered thickness profile. The system may perform, after performing the uptapering removal process, a bundling process to bundle the signal fiber and a set of one or more pump fibers in a bundle configuration. The system may perform, after performing the bundling process, a bundle unification process to cause the bundle configuration to form a unified bundle configuration. The system may perform, after performing the bundle unification process, an attachment process to cause an end of the unified bundle configuration to attach to an end of an output fiber.

Abstract: In some implementations, a fiber amplifier system includes a fiber oscillator and a fiber amplifier coupled to an output end of the fiber oscillator. The fiber oscillator may include an active fiber having a first end and a second end, where the active fiber is to receive pump light from one or more optical sources; one or more high-reflectivity mirrors coupled to the first end of the active fiber; and multiple output coupler mirrors coupled to the second end of the active fiber. The one or more high-reflectivity mirrors and the multiple output coupler mirrors may form an optical cavity with the active fiber for generating laser light. The multiple output coupler mirrors may have respective center wavelengths that are different. The multiple output coupler mirrors may have respective reflection spectrums that are different.

Abstract: A monitoring device may receive sensor information, associated with an optical device included in a high-power fiber laser, from a set of sensors associated with the optical device. The monitoring device may determine, based on the sensor information, a set of operational properties of the optical device. The set of operational properties may include: a health property that describes a health of one or more components of the optical device, a degradation property that describes degradation of one or more components of the optical device, an environmental property that describes an environment of the optical device, or a process property associated with a process in which the optical device is being used. The monitoring device may identify whether an operational property, of the set of operational properties, satisfies a condition, and may selectively perform a monitoring action based on whether the operational property satisfies the condition.
