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 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.
