Device for integrating and transmitting different-wavelength multi-path lasers and use method thereof

The invention discloses a device for integrating and transmitting different-wavelength multi-path lasers and a use method of the device for integrating and transmitting the different-wavelength multi-path lasers. The device for integrating and transmitting the different-wavelength multi-path lasers comprises a plurality of laser shaping fiber-based feeding devices. Each laser shaping fiber-based feeding device is communicated with a fused biconical taper beam combiner through an input optical fiber. The fused biconical taper beam combiner is communicated with a laser shaping fiber discharging device through an output optical fiber. The use method of the device for integrating and transmitting the different-wavelength multi-path lasers comprises the following steps that firstly, when the device is used for the first time, collimation is conducted on a laser beam output by a laser device, and then the fiber-based feeding is conducted on the laser beam; secondly, a laser beam output by the fused biconical taper beam combiner is shaped; thirdly, when the device is used again, fine adjustment is conducted on collimation of the laser beam. The device for integrating and transmitting the different-wavelength multi-path lasers is simple in composition, convenient to adjust, high in flexibility, good in repeatability, and high in transmission efficiency.
