Claims

[Claims for Utility Model Registration] 1. A connector provided at the end of an optical fiber into which a high-energy beam is to be incident, which is fitted onto the end of the optical fiber and extends from the end face of the optical fiber over a required length in the axial direction. The core member includes a large diameter portion having an inner diameter larger than the diameter of the optical fiber to separate a gap between the core member and the peripheral surface, and an optical fiber support portion having an inner diameter approximately equal to the diameter of the optical fiber. 1. A high-energy beam connector, characterized in that at least the inner peripheral surface of the large diameter portion is made of ceramic. 2. The high-energy beam connector as set forth in claim 1, wherein the core member is made of ceramic. 3. The height according to claim 1, wherein the end face of the optical fiber support portion facing the gap is inclined so as to recede from the end face of the optical fiber as it goes from the center side to the peripheral side. Energy beam connector. 4- Inclination angle θ of the end face of the optical fiber support part
The high-energy beam connector according to claim 3, wherein is expressed by the following formula. θ≦90°−arc tan (a/b However, a:
Difference between the inner diameter of the core member and the diameter of the optical fiber 172b: Distance from the tip end face of the core member to the end face of the support portion.
