Since the turn of the century, China has been a research hub for fiber lasers. The National University of Defense Technology's research into fiber lasers began during the "11th Five-Year Plan" period and has lasted approximately 15 years, yielding a number of peer-reviewed research outputs. The optical engineering field underpins the majority of fiber laser research at the institution. Optical engineering is one of the university's dominating fields, with good results in recent discipline review, providing a high-level scientific research platform and talent team for fiber laser research. On the other hand, fiber laser development benefits from the advantages of reasonably complete subject categories as well as helpful exploration and practice in interdisciplinary aspects. From an interdisciplinary standpoint, this paper sorts out several important breakthroughs in the interdiscipline of fiber laser and electronics, materials, control, intelligence, nano, and other disciplines in the university, and analyzes the opportunities faced by interdisciplinary scientific research and interdisciplinary construction from four perspectives: the evolution of scientific research paradigm, subject driving, application demand traction, and the inception of interdisciplinary scientific research and interdisciplinary construction.The National University of Defense Technology's main fiber laser research is based on the discipline of optical engineering; Research in the fiber laser began during the "11th Five-Year Plan" period, has been about 15 years, and has achieved a series of peer-recognized research results. During the "11th Five-Year Plan" period, the university concentrated on scientific research in the fields of fiber laser coherent synthesis and supercontinuum fiber light source, and officially began related work in the fiber laser discipline, achieving research achievements represented by kilowatt fiber laser coherent synthesis system and high-power near-infrared supercontinuum light source. During the "12th Five-Year Plan" period, the university focused on high-power fiber lasers, gradually expanding its research into high-power fiber lasers, fiber passive devices, and so on, and achieved innovative results in cascade pumping high-power fiber lasers, special wavelength fiber lasers, high-brightness laser bunders, and high-power ultrafine lasers. Since the "13th Five-Year Plan," the research focus has shifted to the development of laser fiber materials and software, as well as the development of laser full machines to form a complete chain. As a representative of the corporation, we have obtained independent intellectual property software, virtual simulation courses, various types of laser fiber, high power and high beam quality single frequency/narrow linewidth/broadband fiber laser, cascade pump/semiconductor direct pump high power and high beam quality fiber laser, high power visible light/near infrared/mid-infrared supercontinuum light source, thousand-beam laser phase control/high power fiber coherent synthesis system. This study examines the prospects for cross-disciplinary research and construction from four perspectives: the growth of scientific research paradigms, subject driving, application demand pulling, and science-education integration. The university's fiber laser approach has produced a number of notable research results, with input from other disciplines playing an essential role. The in-depth analysis, however, reveals that relevant research is primarily "reference" and "inspiration" between disciplines, such as the development of fiber simulation software mentioned in the introduction and ultra-long-term stable high-performance pulsed fiber laser, etc., which is more the result of personnel familiar with "optical engineering," "software engineering," and "nanoscience" working together to promote. In reality, there aren't many cross-disciplinary construction and cross-scientific research items. There are basically no examples like Logan Wright who have made significant contributions to various disciplines such as nonlinear fiber optics and artificial intelligence at the moment. The scientific foundation of relevant researchers must be strengthened further. However, with the rapid advancement of a new round of scientific and technological revolution, industrial change, and continuous innovation of education and teaching methods, it provides new opportunities for cross-scientific research and cross-disciplinary construction, as well as a broad space for the development of the fiber laser direction, and the fiber laser direction will continue to produce more innovative results.After approximately 15 years of development, the university's research of fiber laser has accomplished a number of significant outcomes that are strongly tied to the support of the optical engineering discipline and the deep cross-integration of other associated disciplines. The continuous human science and technology development in this century is continuous comprehensive development, from comprehensive to more comprehensive, and this integration tendency is reflected in scientific research, discipline construction, personnel training, and other aspects. Although the development of fiber laser has experienced many problems and challenges, the research of fiber laser will continue to create more novel outcomes with the continued advancement of interdisciplinary construction and cross-scientific research.
