Preface to Special Issue on “Remote Power Transmission Technologies Using Laser”

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.
