Power on-line monitoring and bleaching integrated fiber laser system

The invention discloses a power online monitoring and bleaching integrated fiber laser system, and belongs to the technical field of fiber laser. The structure comprises a tail fiber red light source (1), an optical fiber coupling acousto-optic modulator (2), an optical fiber beam splitter (3), a tail fiber semiconductor laser (4), a tail fiber blue-violet light source (5), an optical fiber beam combiner (6), a high-reflectivity fiber bragg grating (7), an ytterbium-doped gain optical fiber (8), a low-reflectivity fiber bragg grating (9), a cladding light filter (10), an end cap (11), a dichroic mirror (12), a delay modulation module (13), a balance detection module (14) and a control module (15). The laser output power change is monitored on line by detecting the light power change, the bleaching light source is controlled to be turned on and turned off in real time according to the detection result, laser power on-line monitoring and power compensation are achieved, the stability of the fiber laser is impro
