The meeting was chaired by the Director of Advanced Manufacturing Division of High Technology Research and Development Center of the Ministry of Science and Technology, Au and Jian. The acceptance expert group and relevant leaders listened carefully to the report of the project leader, researcher Liu Jianguo, and the project team on the mid-term completion of the project. After the report, the acceptance panel and relevant leaders inspected the R&D and production site of the project unit and watched the live demonstration of the project prototype.

During the implementation of this project, the project team developed the core components of high concentration doped glass, two kinds of glass special fiber, semiconductor gain chip and other "neck", and broke through the design and preparation of semiconductor gain chip and efficient packaging coupling, the preparation of low-loss high-gain glass fiber and narrow line width fiber laser amplifier nonlinear effect suppression The key technologies such as the design and preparation of semiconductor gain chips and high-efficiency packaging coupling, the preparation of low-loss high-gain glass fiber and the suppression of nonlinear effects of narrow linewidth fiber laser amplifiers have been developed.
