Long term commitment to research on ultrafast laser precision detection and processing applications, especially in the field of laser-induced breakdown spectroscopy (LIBS) for environmental monitoring and deep space exploration. We have developed a new technology of femtosecond plasma grating induced spectroscopy (GIBS), which has increased the detection sensitivity to unprecedented ppb levels internationally. This has enabled us to integrate and realize the world's first set of highly sensitive GIBS detection systems, overcome matrix effects, and achieve innovative applications such as self calibration of soil and liquid trace analysis. We have also collaborated with the China Aerospace 504 Institute to conduct ground validation experiments for GIBS trace analysis of Martian and lunar surface materials, providing technical support for deep space exploration and asteroid exploration. The development of multidimensional plasma grating breakdown spectroscopy (MIBS) and femtosecond fiber plasma grating synergistic breakdown spectroscopy (F-GIBS) series of trace spectral detection methods has brought important breakthroughs to the in-depth development and application of laser spectroscopy technology. The development of new laser source technologies such as fiber solid hybrid amplification, adaptive start-up, and time-frequency self similarity amplification has been successfully applied in the development of scientific instruments for precision measurement and processing in China, and has played an important role in industries including precision measurement and micro/nano manufacturing. Developing volume plasma grating technology for femtosecond laser direct writing processing, applied to SiC wafers, semiconductor material processing, polishing, and detection. Developing GHz pulse train mode femtosecond laser can be applied to precision machining, polishing, and slotting of semiconductor materials such as 12 inch silicon wafers. We adopt multidimensional spatiotemporal spectral light field modulation technology to develop large-scale, high-precision, high-efficiency, low-cost, pollution-free, nationally produced silicon wafer laser polishing equipment. This application is forward-looking and pioneering for national strategic needs, covering multiple fields such as principles, technology, and overall equipment, in order to improve the efficiency and quality of silicon wafer polishing processes. The relevant achievements have been published in top optical journals such as Adv. Photonics, first tier journal Laser Photonics Rev., and J. Anal. Atom. Spectrum.
