Researchers at the University of Illinois at Urbana Champaign have developed compact visible wavelength achromatic mirrors using 3D printing and porous silicon, which are crucial for miniaturization and lightweight optical devices. These high-performance hybrid micro optical devices can achieve high focusing efficiency while minimizing volume and thickness. In addition, these microlenses c...
Beijing, April 1st (Reporter Liu Xia) - The world's most powerful laser has been activated recently. On March 31st, the Physicist Organization Network reported that the system can enable laser pulses to reach a peak of 10 terawatts (1 terawatt=100 terawatts=1015 watts) within 1 femtosecond (1000 trillions of a second), which is expected to promote revolutionary progress in multiple fi...
Recently, Shao Jianda, a researcher of Shanghai Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Jin Yunxia, a researcher team, and Li Chaoyang, a researcher of Zhangjiang Laboratory, have made breakthroughs in the field of ultra wideband pulse compression gratings.The research team has successfully developed a ultra 400 nm broadband gold grating for single cycle pulse com...
Refractory material can withstand high temperature above 1500℃. They are essential materials for industrial furnaces that produce glass or ceramics, non-ferrous metals and steel. The service life of manufactured refractory products can range from a few days to many years, depending on the material, the temperature in the melting vessel and other operating parameters. As a result, although ...
Professor Zhang Huaijin and Yu Haohai from the Institute of Crystal Materials of Shandong University (the State Key Laboratory of Crystal Materials) proposed a spatial harmonic modulation strategy, which realizes the phase matching conditions that can be manipulated artificially in the new quartz crystal, and realizes the effective frequency doubling within the VUV range. The relevant research is ...
