On July 23, the national key R&D program “Additive Manufacturing and Laser Manufacturing” key special project “High-power semiconductor lasers for manufacturing” project “Semiconductor Laser Testing and Demonstration Application in Additive Manufacturing and Laser Manufacturing Equipment” was held. .
The meeting was organized by the project lead unit, Suzhou Changguang Huaxin. First, Liao Xinsheng, the head of the project, introduced the overall situation of the project, and then the heads of each project introduced the completion of the project.
Ma Yunfeng, a senior engineer at the Aerospace Information Innovation Research Institute (hereinafter referred to as the “Sky Institute”), introduced in detail the “semiconductor laser testing and in “Additive Manufacturing and Laser Manufacturing Equipment Demonstration Application” project performance evaluation, and conducted in-depth discussions and exchanges with the project team.
The expert group affirmed the technical achievements obtained by the research group, and put forward constructive opinions and suggestions, agreeing that the subject has completed the predetermined research content and assessment indicators, and achieved the expected goals.
In this topic, the Institute of Aeronautics and Astronautics is responsible for the research of comprehensive semiconductor testing methods, innovatively proposed the line scanning laser parameter testing technology, and developed a high-power semiconductor comprehensive testing system based on integrating spheres, which can realize the online quality of single DAR after packaging in a stacked array. Testing; Complete the research on comprehensive evaluation methods and comprehensive testing tasks of 10,000-watt semiconductor lasers, solve the problem of comprehensive testing of large divergence angle and large aperture semiconductor lasers, and provide common key testing technologies and services for the smooth development of the project.
Project leader Ma Yunfengzheng, senior engineer, reported the overall situation of the project
