Patent ID: 11936156
Assignee: FURUKAWA ELECTRIC CO., LTD.
Field: Optics (Instruments)
Classification: CPC H  F | IPC H

Claim 2:
3. An optical power transmission apparatus, comprising:
a light emitting unit including 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, wherein
the second light reflecting means is arranged nearer to the light receiving means than the optical fiber is,
a first laser resonator is formed, between the first light reflecting means and the second light reflecting means, by optical connection between the first optical gain generating means and the optical fiber,
first laser light generated by the first laser resonator is configured to be incident on the light receiving means,
the second light reflecting means and the light receiving means are fixed to each other to form a light receiving unit,
the light receiving unit includes a second laser resonator, and a second optical gain generating means that is arranged in the second laser resonator and generates optical gain by being supplied with energy,
the second optical gain generating means receives the first laser light and generates optical gain, and
laser oscillation is caused by the second laser resonator, and second laser light generated by the laser oscillation is configured to be output from the second laser resonator.
