Recently, the team of Yang Tao-Yang Xiaoguang, a researcher at the Key Laboratory of Materials Science of the Institute of Semiconductors of the Chinese Academy of Sciences, and Lu Dan, a researcher, together with Ji Chen, a professor at the Zhijiang Laboratory of Zhejiang University, have made important progress in the research of high-power, low-noise quantum dot DFB single-mode lasers.Distribut...
In a groundbreaking scientific study published in Volume 13 of the Scientific Report, researchers reported on the results of Young's double slit interference experiment using oscillating vortex radiation under a photon counting system. The experiment involves using a spiral oscillator to emit second harmonic radiation in the ultraviolet range. Using an ultra narrow bandpass filter in the low curre...
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,...
On quartz sheets, the angular rhombic boron nitride crystals with a thickness of only 1 to 3 microns are as thin as cicada wings, but their energy efficiency is 100 to 10000 times higher than traditional optical crystals. At the opening ceremony of the 2024 Zhongguancun Forum Annual Conference held on April 25th, the world's thinnest known optical crystal was listed as one of the top ten technolog...
Terahertz waves have significant application value in communication and imaging. The nonlinear interaction between strong field ultrafast laser and matter is one of the important ways to generate terahertz waves. The experimental and theoretical research related to terahertz generation media such as plasma, gas, and crystal is relatively sufficient. However, liquid water is a strong absorbing medi...
