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.
