Scientists at the City University of New York use tiny nitrogen defects in the atomic structure of diamonds as "color centers" to write data for storage. This technology is published in the journal Nature Nanotechnology and allows for encoding multiple bytes of data into the same nitrogen defect at multiple optical frequencies, without confusing the information content.The common laser based techn...
Recently, NUBURU, a supplier of high-power and high brightness industrial blue laser technology in the United States, announced that it has reached bridge loan agreements ("bridge loans" or "bridge financing") with existing and new institutional investors.The principal of this bridge financing is $5.5 million, aimed at providing funding for the company until it obtains long-term credit financing,...
Nowadays, lasers that emit extremely short flashes can be found in many research laboratories, but they usually fill the entire room. Physicists have now successfully reduced this laser to the size of a computer chip. As they reported in the journal Science, their research can lay the foundation for extremely compact detectors.A team led by Qiushi Guo from the California Institute of Technology in...
Researchers from Chalms University of Technology in Sweden have successfully improved the efficiency of optical microcombiners, making them a high-performance laser. This breakthrough will have a wide impact in fields such as space science and healthcare.The two rings in the figure are micro resonators, which play a crucial role in the implementation of efficient micro combs.The importance of micr...
1. Research backgroundDirected energy deposition (DED), as an efficient and economical technology in the field of additive manufacturing (AM), is widely used in the manufacturing of metal materials. However, its high heating and cooling rates, as well as significant temperature gradients, often lead to rapid solidification, forming cross layer columnar grains and internal defects, seriously affect...
