Abstract: A fiber laser system monitor includes a fiber laser adapted to generate fiber laser light, a first light emitter adapted to generate first emitted light, a photodiode adapted to receive the first emitted light and the fiber laser light and to generate a received light signal responsive thereto, and a controller connected to the fiber laser, the first light emitter, and the photodiode. The controller receives the received light signal. The controller is configured to determine an acceptable operation for the fiber laser, the first light emitter, and the photodiode by comparing the received light signal with a predetermined maximum threshold and with a predetermined minimum threshold.

Abstract: A magnetically-actuated laser beam control assembly may include a magnetically permeable cover arranged to sealingly couple to an optics housing to cover an opening of the optics housing, an interior sub-assembly, and an exterior sub-assembly. The interior sub-assembly may include includes a linkage having a first section and a second section; the first section of the linkage to receive an optical component; and a ferroelectric or ferromagnetic material on the second section of the linkage. The exterior sub-assembly may include an electromagnet energizable to impart a magnetic force to the ferroelectric or ferromagnetic material to move the optical component from one of a resting position and a different position to the other of the resting position and the different position to cause the optical component to selectively optically process a laser beam. Other embodiments may be disclosed and/or claimed.
