Abstract
Provided is an optical fiber for producing heat wherein a reflection tube (13) is wrapped on its outer peripheral surface by a heat conduction tube (14) to block laser beam from being irradiated outside, and a plurality of grooves are formed on a side of an optical fiber (11) so as to transmit laser beam to the side of the optical fiber (11) at 360° around a central axis of the optical fiber (11) where a cloth (12) is peeled away such that the area where heat is produced is expanded to a whole length direction of the optical fiber (11) where the cloth (12) is peeled away between the optical fiber (11) and the reflection tube (13).
Claims7
An optical fiber assembly for producing heat, comprising:
- an optical fiber;
- a reflection tube wrapped on an outer peripheral surface of the optical fiber by a heat conduction tube to block laser beam from being irradiated outside;
- and
- a plurality of grooves disposed on a side of the optical fiber so as to transmit laser beam to the side of the optical fiber at 360° around a central axis of the optical fiber,
- wherein a cloth is peeled away such that an area where heat is produced is expanded to a whole length direction of the optical fiber where the cloth is peeled away between the optical fiber and the reflection tube.
A method for manufacturing an optical fiber assembly for producing heat, comprising:
- a first step of forming two or more reflection type grooves or two or more circular grooves, or forming in combination two or more grooves of the reflection type grooves and the circular grooves in a conical shape with respect to a side of an optical fiber by processing precisely the side of the optical fiber while peeling away a cloth at one side of the optical fiber and adjusting a horizontal angle around a central axis of the optical fiber;
- and
- a second step of enveloping the optical fiber where the cloth is peeled away with the reflection tube and then wrapping additionally an outside of the reflection tube with a heat conduction tube thereby to block laser beam from being irradiated outside and produce heat within the reflection tube, and bonding the reflection tube and the heat conduction tube so as to prevent the reflection tube from being detached.
An optical fiber assembly for producing heat, comprising:
- an optical fiber;
- at least one of a reflection tube and a heat conduction tube wrapped so as to prevent laser beam transmitted through the optical fiber from being irradiated outside;
- and
- a plurality of grooves disposed on a side of the optical fiber so as to transmit laser beam to the side of the optical fiber at 360° around a central axis of the optical fiber,
- wherein a cloth is peeled away such that an area where heat is produced is expanded to a whole length direction of the optical fiber where the cloth is peeled away between the optical fiber and the reflection tube.
