Driven by the pioneering work of scientists such as John Young Hall, significant progress has been made in precision measurement in the field of laser physics. His contribution to laser frequency stability and precise measurement using lasers has led to groundbreaking techniques that significantly reduce residual amplitude modulation.John Hall's research focuses on understanding and manipulating s...
OLED is located at the top and is formed by an organic layer between the contacts. Apply voltage to it, inject charge and generate light, which in turn excites organic laser. Organic lasers contain a grating that can generate feedback and diffract some of the laser out of the structure.Organic laserResearchers have created the first organic semiconductor laser to operate without the need for a sep...
From May 15 to 17, 2025, the 20th Wuhan Optoelectronics Expo will be held grandly at the China Optics Valley Convention and Exhibition Center in Wuhan. With the theme "Light Connects Everything, Intelligence Leads the Future," this year's expo will focus on six major fields: laser technology and applications, optics and precision optics, information communication and semiconductors, automotive opt...
μ Mesons are naturally occurring subatomic particles that can penetrate much deeper dense matter than X-rays. Therefore, μ Meson imaging can enable scientists to capture images of nuclear reactors, volcanoes, tsunamis, and hurricanes. However, this process is slow, as it occurs naturally μ The low flux of mesons requires several months of exposure time for the image.It is understood that ...
Recently, the High Power Laser Element Technology and Engineering Department of the Shanghai Institute of Optics and Mechanics, Chinese Academy of Sciences, has made progress in the research of picosecond reflectors based on composite materials. The relevant research results are titled "Hybrid material based mirror coatings for picosecond laser applications" and published in Optics and Laser Techn...
