Abstract
In this special issue, the characteristics of the system and the device, the necessary technology, and the
latest trends of the optical wireless and the optical fiber power transmission which utilize the energy of
the laser light remotely as electric power are discussed. It is easy to imagine the principle and features
of power transmission by laser light. However, this technical field is an unexplored laser application
field which has not been sufficiently developed the system and application. It should be noted that
remote wireless power transmission may become one of important application fields of lasers in the
future.
