Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Patent Application No. 63/335,573, filed on Apr. 27, 2022. BACKGROUND OF THE INVENTION Field of The Invention The disclosure of the present patent application relates to unmanned aerial vehicles, and particularly to an unmanned aerial vehicle carrying an optical device which is tethered to an external light source. Description of Related Art Laser systems and other systems which generate directed light are used for a wide variety of different applications. Examples of such applications include energy-based weapon systems, welding or heating applications, distance measurement, chemical analytics, particle analytics, object targeting and disruption of target optical systems. Conventionally, such systems are standalone devices or integrated into stationary devices. As such, such systems are limited in their usage because they must be used either at their permanent installation sites, or they must be painstakingly disassembled, moved and then reassembled. Although portable laser systems are known, such systems typically have very low power outputs and are conventionally used for little more than recreational purposes. There is a need for making higher power laser systems more portable and usable over a wider field of applications. Thus, an unmanned aerial vehicle tethered with an optical fiber solving the aforementioned problems is desired. SUMMARY OF THE INVENTION The unmanned aerial vehicle (UAV) tethered with an optical fiber is an unmanned aerial vehicle, drone or the like carrying an optical device which is tethered to an external light source. As a non-limiting example, the light source may be a ground-based laser. The optical device is connected to, and optically coupled with, the light source by a tether including at least one optical fiber. A stabilizer may be mounted on the optical device for stabilizing orientation and direction thereof.
