The optical properties of photonic crystals are closely related to their lattice constants, which are usually required to be in the same order of magnitude as the operating wavelength. In a crystal material, the photonic crystal structure is formed by the periodic arrangement in space of units whose dielectric constant is different from that of the crystal itself, and whose lattice constant depend...
Driven by the global trend of lightweighting in new energy vehicles (NEVs), TRUMPF has reached a significant milestone in Taicang, Jiangsu—the successful rollout of the 100th TruLaser Cell series 3D five-axis laser cutting machine. This achievement is more than just a numerical breakthrough; it symbolizes the deep integration of German technology with Chinese manufacturing and underscores TRUMPF's...
By using a new type of laser, the processing speed of wafers can be 10 to 20 times faster than before. This is the result of a research project at the Fraunhofer Institute for Solar Systems in Germany.Researchers have developed a prototype that can use ultraviolet waves to carve the most intricate structures on silicon wafers. The new system concept enables solar cell manufacturers to perform lase...
Recently, according to the journal Nature Nanotechnology, a team from the California Institute of Technology reported that they have constructed a metasurface covered with micro adjustable antennas that can reflect incident light beams: one beam of light enters and multiple beams of light exit, each with a different frequency and propagating in a different direction. This is a new method for proce...
Recently, the research team of the High Power Laser Physics Joint Laboratory at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made significant progress in the study of single shot characterization technology for complex combination laser pulses. The research team utilized an improved broadband transient grating frequency resolved optical switch technology (T...
