Abstract

The invention provides a dual-wavelength optical fiber coupling laser pumping source. The dual-wavelength optical fiber coupling laser pumping source comprises a first laser chipset, a second laser chipset and a gain optical fiber, the first laser chipset comprises a plurality of first laser chips; the second laser chipset comprises a plurality of second laser chips; and each first laser chip andeach second laser chip are communicated with the gain optical fiber through the energy transmission optical fiber. The dual-wavelength optical fiber coupling laser pumping source provided by the invention is provided with two laser chipsets with different spectral wavelengths, two different pumping wavelengths are generated through one semiconductor pumping source, the semiconductor pumping sourceis communicated with the gain optical fiber, and a space coupling device does not exist, so that the laser is compact in structure; and meanwhile, the energy level transition of particles in the gainoptical fiber is fully utilized, and the requirements of different pumping sources are met. In the high-power ytterbium-doped fiber laser, the stability of the laser output power can be ensured, andthe nonlinear threshold in the laser can be improved.

Description

technical field [0001] The invention relates to the technical field of fiber lasers, in particular to a dual-wavelength fiber-coupled laser pump source. Background technique [0002] With the gradual development of the industrial manufacturing market, the demand for fiber lasers as the main part of the high-power laser market continues to increase. A fiber laser is mainly composed of a pump source, a gain fiber and a resonator. The semiconductor laser is the main pump source of the fiber laser. The semiconductor pump source laser is injected into the gain fiber through a fiber combiner, and the doped particles in the gain fiber absorb The pump light emits long-wavelength laser light through energy level conversion, and outputs it through the oscillation of the resonant cavity. Therefore, the choice of pump wavelength determines the conversion efficiency and emission wavelength of the laser. [0003] The selection of the wavelength of the pump source in the fiber laser is m...
