PROBLEM TO BE SOLVED: To provide an optical amplification component for enhancing the life of an optical fiber for amplification, and to provide a fiber laser device.SOLUTION: An optical amplification component 1 includes a heat dissipation plate 10, and an optical fiber 20 for amplification arranged on the heat dissipation plate 10. The optical fiber 20 for amplification has a first section SC1 where a fiber part 20A extending from a reference position RP between one end E1 and the other end E2 of the optical fiber 20 for amplification toward the one end side, and a fiber part 20B extending from the reference position RP toward the other end side are arranged in one direction from the reference position RP, and a second section SC2 where the fiber parts 20A, 20B surround the outside of the first section SC1 after being arranged in one direction. The rims at one end and the other end of the optical fiber 20 for amplification are separated from the side face of the surrounding side face. |
