Document Type and Number:
WIPO Patent Application WO/2020/032148
Kind Code:
A1
Abstract:
This optical power transmission device is provided with: a light emitting unit which is provided with a first optical gain generating means and a first light reflecting means; an optical fiber; a second light reflecting means; and a light receiving means. This optical power transmission device is configured such that: the second light reflecting means is arranged closer to the light receiving means than the optical fiber; a first laser resonator is configured by optically coupling the first optical gain generating means and the optical fiber to each other between the first light reflecting means and the second light reflecting means; and a first laser beam generated by the first laser resonator is incident on the light receiving means.
