Description

technical field [0001] The invention relates to a biological special band broadband pulse light source, in particular to a 1.7 μm band broadband picosecond pulse multi-wavelength optical fiber light source, which belongs to the field of biomedical light sources. Background technique [0002] The 1.7μm band is in the trough between the two water absorption peaks of 1.45μm and 1.9μm, and it is also in the high absorption peak of fat and collagen. Since biological tissues contain a large number of water molecules, the detection imaging instrument based on the 1.7μm band light source has low absorption loss and large imaging depth. Therefore, the 1.7μm band light source has important applications in optical coherence tomography (OCT), multiphoton fluorescence microscopy (MFLM), laser surgery and other fields. In addition to biomedical research, since the 1.7μm band covers the resonance band (1720nm) of some polymer molecules, it can be used for laser processing and laser shapin...
