On July 16, according to the Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences, the research teams of Shao Jianda and Jin Yunxia from the High Power Laser Component Technology and Engineering Department made new progress in mid-infrared high-power continuous laser spectral fusion research. The relevant research results were published in Optics Letters. The research team proposed a splicing grating spectral bundling architecture to achieve efficient bundling of multiple mid-infrared lasers through distributed splicing of multiple small-aperture sub-gratings within an equivalent large-aperture grating space. The study provides a new technical path for the expansion of mid-infrared multi-channel spectral beamforming systems from tens of watts to 100 watts, and also provides a reference for the construction of multi-band high-power laser platforms from visible light to terahertz.
