In the same groove structure, the curvature radius of the first arc structure 231 is greater than that of the second arc structure 232. From inside to outside, in the adjacent two groove structures, the curvature radius of the second arc structure 232 in the outer groove structure is greater than that of the first arc structure 231 in the inner groove structure, so as to greatly change the transmission direction of the transmission light in the inner cladding of the optical fiber, to achieve the purpose of reducing the spiral light component in the inner cladding of the optical fiber to the maximum extent in a shorter optical fiber length, thereby improving the absorption and utilization efficiency of the pump light in the inner cladding structure, and improving the optical efficiency and electrical efficiency of the laser.

[0055] The protective shell 300 is provided with a heat dissipation assembly; the heat dissipation assembly can include at least one of heat dissipation teeth or heat dissipation flow channels to increase the heat dissipation area and improve the heat dissipation efficiency.

[0056] It should be understood that the specific structure of the heat dissipation assembly is not limited in the present application, and only the protective shell 300 can balance the heat dissipation capacity and protection capacity of the optical fiber 400; wherein the heat dissipation assembly includes but is not limited to heat dissipation teeth and heat dissipation flow channels and other heat dissipation structures that avoid direct exposure of the optical fiber 400 to the air, so that the protective shell 300 can balance the heat dissipation capacity and protection capacity of the optical fiber 400.
