Abstract
The invention discloses a single-tube semiconductor laser and fiber coupling system which comprises single-tube semiconductor lasers, a coupling device and a fiber. The single-tube semiconductor lasers are arranged on at least two arcs at a first preset interval in the slow-axis direction, so that laser light from the single-tube semiconductor lasers is emitted from the radii of the arcs to the circle center; the at least two arcs are concentric; the single-tube semiconductor lasers are arranged on at least two steps in the fast-axis direction, and the single-tube semiconductor lasers of the same arc are arranged on the same step, so that laser light emitted by the single-tube semiconductor lasers is gathered at the circle center; the coupling device is arranged at the circle center; and the light incident end of the fiber is arranged at the position where laser output by the coupling device is gathered. The system solves the problems that in the prior art, the aperture of a focusing mirror is not used sufficiently, the amount of single-tube semiconductors is limited, and the laser output power is low.
Description
technical field [0001] The invention relates to the field of optics, in particular to a single-tube semiconductor laser fiber coupling system. Background technique [0002] As a packaging form of semiconductor lasers, single-tube semiconductor lasers have the advantages of better heat dissipation characteristics, longer life, and narrower light-emitting bar width compared with semiconductor laser bars. Since the single-tube semiconductor laser packages each light-emitting unit of the semiconductor laser independently, if you want to achieve high-power laser output, you must use multiple modules for beam combining. Because the beam quality of semiconductor lasers is poor, and the beam quality does not match in the direction of the fast axis and the slow axis, then coupling and focusing the semiconductor laser into an optical fiber can effectively improve the beam quality of the semiconductor laser through flexible transmission through the optical fiber. [0003] At present, ...
