High-power fiber laser

The invention discloses a high-power fiber laser which comprises a light condensation assembly, a plurality of generators and position adjusting assemblies, the central axis of the light condensation assembly serves as the optical axis, the generators and the position adjusting assemblies are circumferentially and evenly distributed with the optical axis as the axis, the number of the generators and the number of the position adjusting assemblies are the same, and circumferential angle positions are in one-to-one correspondence. The generator emits a single laser beam towards the light condensation assembly, the position adjusting assemblies adjust the single laser beam penetrating through the position adjusting assemblies and adjust the radial distance relative to the optical axis, all laser beams passing through the position adjusting assemblies are located on the same center circle with the optical axis as the axis, and the light condensation assembly compresses all the laser beams inwards in the circumfer
