1. An optical device included in a high-power fiber laser, the optical device comprising:
a plurality of optical components comprising:
a group of input fibers,
a tapered waveguide,
a splice,
an output fiber attachment component, and
an output fiber; and
a set of sensor components, the set of sensor components comprising:
at least one degradation sensor associated with a degradation property, the at least one degradation sensor comprising:
a photodiode arranged to measure scattered light at or near the output fiber attachment component;
a stress sensor arranged to measure stress at or near the output fiber attachment component; or
a camera arranged to identify hot spots at or near at least one of the tapered waveguide, the splice, or the output fiber attachment component; and
at least one health sensor associated with a health property, the at least one health sensor comprising:
a temperature sensor and a power monitor arranged to measure optical power associated with at least one of the tapered waveguide or the splice; or
a photodiode arranged to measure scattered light at or near at least one of the group of input fibers or the output fiber; and
wherein at least one of the set of sensor components is configured to provide sensor output to an operational monitor associated with the optical device.
