This week, an illustration was published on the cover of the international journal Science, showcasing a powerful mode-locked laser emitted from a miniature photonic semiconductor.A research team led by Alireza Marandi, a professor of electrical engineering and applied physics at the California Institute of Technology, has successfully developed a conventional mode-locked laser large enough to fit...
Recently, researchers have developed a comb laser with higher stability and efficiency. The use of synthetic reflection self injection locking micro comb design enables the laser to achieve stability and increase conversion efficiency by more than 15 times. This efficient, stable, and easy to manufacture design is expected to make rapid progress in fields such as portable sensors, autonomous navig...
The researchers estimate the period from 2023 to 2028. EUV lithography will address the limitations of traditional optical lithography, which has reached its physical limits in terms of resolution. The shorter wavelength of EUV light allows for the creation of smaller features and tighter patterns on silicon wafers, enabling the manufacture of advanced microchips with greater transistor densities....
In order to successfully 3D print metal parts to meet the strict specifications required by many industries, it is necessary to optimize process parameters, including printing speed, laser power, and layer thickness of deposited materials.However, in order to develop additive manufacturing process diagrams that ensure these optimal results, researchers have to rely on traditional methods, such as ...
The use of photons to directly or indirectly drive chemical reactions has fundamentally changed the field of nanomaterial synthesis, leading to the emergence of new sustainable laser chemistry methods for manufacturing micro - and nanostructures. The incident laser radiation triggers complex interactions between chemical and physical processes at the interface between solid surfaces and liquid or ...
