Recently, the reporter learned from Changguang Satellite Technology Co., Ltd. (hereinafter referred to as "Changguang Satellite") that the company used a self-developed vehicle mounted laser communication ground station to conduct satellite ground laser high-speed image transmission experiments with the onboard laser communication terminal of the "Jilin No.1" constellation MF02A04 satellite and ac...

A new laser generation method: a laser without a reflector. This study, conducted by a team of physicists from the University of Innsbruck and Harvard University, shows that quantum emitters with spacing smaller than the wavelength can achieve constructive synchronization of photon emission, resulting in bright and extremely narrow bandwidth beams, even without any optical resonant cavities.The ac...

It is reported that the research team of California Institute of Technology has developed an additive manufacturing (AM) technology based on hydrogel injection, which uses two-photon lithography technology to produce 3D metal with a characteristic resolution of about 100 nm.The relevant research is published in the journal Nano Letters, titled 'Suppressed Size Effect in Nanopillars with Hierarchy ...
