In November 2024, based on the mutual trust and cooperation over the past years, the Munich Shanghai Optical Expo and the Light Academic Publishing Center of the Changchun Institute of Optics, Precision Mechanics and Physics, Chinese Academy of Sciences (hereinafter referred to as the "Light Center") reached a consensus on further strategic development as they ushered in the year of disruptive sci...
The project of the National Natural Science Foundation of China (Jilin Province) "Multicolor Transparent Silicate Garnet Fluorescent Ceramics for Laser Lighting" presided over by Zhang Jiahua, a researcher in the State Key Laboratory of Luminescence and Applications of Changchun Institute of Optics and Fine Mechanics, has made breakthrough progress, developed green fluorescent transparent ceramics...
Recently, Zhang Weijun, a research team of the Anguang Institute of the Chinese Academy of Sciences, Hefei Academy of Materials, made new progress in atmospheric formaldehyde detection, and the related achievements were published on the international TOP journal Sensors and Actors: B. Chemical under the title of "Portable highly sensitive laser absorption spectrum formaldehyde sensor based on comp...
The deformable mirror used in adaptive optics can instantly correct the static wavefront aberrations and atmospheric turbulence wavefront disturbances of the optical system by changing its surface. This enables the optical system to automatically adapt to changes in the environment and maintain optimal performance. It is widely used in high-resolution astronomical observations, laser atmospheric t...
AbstractDue to the width of the laser melt pool and the sintering effect on the surrounding powder, the experimental size of the selective laser melting (SLM) sample will be larger than the design size, which will greatly affect the dimensional accuracy and surface quality of the thin-walled sample. In order to obtain SLM thin-walled TC11 specimens with precise dimensions, an orthogonal experiment...
