Two photon polymerization is a potential method for nanofabrication of integrated nanomaterials based on femtosecond laser technology. The challenges faced in the field of 3D nanoprinting include slow layer by layer printing speed and limited material selection due to laser material interactions.In a new report in Progress in Science, Chenqi Yi and a team of scientists in the fields of technical s...
EV Group, a leading supplier of wafer bonding and lithography equipment for the MEMS, nanotechnology, and semiconductor markets, and Silicon Austria Labs, a leading electronic systems research center in Austria, announced that SAL has received and installed multiple EVG lithography and photoresist processing systems in its MicroFab at the R&D cleanroom facility in Filach, Austria.These devices...
Recently, the German research institution Fraunhofer ILT team is collaborating with the Department of Optical Systems Technology (TOS) at RWTH Aachen University to develop a testing system aimed at studying complex laser beam profiles using a new platform. This platform can construct customized beam profiles for laser powder melting (PBF-LB) 3D printing, thereby improving part quality, process sta...
We investigated the potential of laser selection in a wide optical range from ultraviolet to visible light, and then to infrared (excitation wavelengths of 325, 532, 785, and 1064 nm), in order to combine and analyze extreme microorganisms related to Earth (such as Cryptomeria elegans, cold floating nematodes, and circular green algae), carbon water compound molecules, as well as simulated mineral...
Recently, the research team of the State Key Laboratory of Intense Field Laser Physics of the Chinese Academy of Sciences Shanghai Institute of Optics and Fine Mechanics has made progress in the research on the repetition rate dependent femtosecond laser air filamentation self focusing threshold. The relevant research results were published in Optics Express under the title "Pulse repetition rate ...
