Since the 1960s, lasers have brought revolutionary changes to the world and have now become an indispensable tool in modern applications, from cutting-edge surgical procedures and precision manufacturing to fiber optic data transmission. However, with the increasing demand for laser applications, challenges have also arisen. For example, the market for fiber lasers is constantly expanding, mainly ...
Recently, the team of Professor Sun Jinhua and researcher Wang Qingsong of the University of Science and Technology of China and the team of Professor Guo Tuan of Jinan University have made important achievements in the field of early warning of thermal runaway optical fiber detection of lithium-ion batteries.A high-precision, multi-mode integrated fiber optic device that can be implanted in...
Us researchers report 8.1 μm wavelength quantum cascade laser (QCL) grown on silicon (Si) by MOCVD [S. Xu et al., Applications. Physics Letters, v123, p031110, 2023]. "There are no previous reports of QCL growth on silicon substrates by metal-organic chemical vapor deposition (MOCVD)," commented the team from the University of Wisconsin-Madison, the University of Illinois at Urbana-Champaign an...
Expanding our scientific understanding often boils down to observing what is happening as closely as possible. Now, researchers from Japan have observed the nanoscale behavior of azo polymer films and triggered them with lasers.In a study published in Nano Express last month, researchers at Osaka University used a combination of cutting-edge scanning high-speed atomic force microscopy and optical ...
According to a report in Nature on June 26th, a team from Stanford University in the United States has developed a titanium sapphire laser on a chip. Whether in terms of scale efficiency or cost, this achievement is a huge progress. Image source: Nature websiteTitanium sapphire lasers are indispensable in many fields such as cutting-edge quantum optics, spectroscopy, and neuroscience, but they ...
