Laser chip manufacturer Shijia Photon will make a profit of 65 million yuan in 2024

Recently, the Advanced Laser and Optoelectronic Functional Materials Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made progress in the research of Nd: ASL (Sr0.7Nd0.05La0.25Mg0.3Al22.7O19) laser crystals, and the related achievements were published in Infrared Physics&Technology under the title of "Tunable laser operations on Nd doped cont...

Researchers from the Laser Energy Laboratory at the University of Rochester led the experiment and demonstrated an efficient "spark plug" for direct driving of inertial confinement fusion. In two studies published in the journal Nature Physics, the team shared their findings and detailed the potential to expand these methods with the aim of successful nuclear fusion in future facilities.LLE is the...

Background IntroductionTwo dimensional materials have attracted widespread attention due to their atomic level thickness and unique properties, such as high binding energy, tunable bandgap, and new electronic degrees of freedom (valley electronics). They have many application prospects in fields such as microelectronics, nanophotonics, and nanoenergy. Various two-dimensional materials have their o...

Optical metamaterials are an effective way to utilize their superior photon capture capabilities. Therefore, perfect absorbers can be achieved through nanoscale resonant plasmas and metamaterial structures.Metamaterial perfect absorbers (MPAs) are typically composed of periodic subwavelength metals (such as plasma superabsorbers) or dielectric resonance units. Compared with static passive physical...

The National Institute of Information and Communication Technology of Japan, Nagoya Institute of Technology, and Japan Aerospace Exploration Agency have achieved the so-called "world's first successful demonstration of next-generation error correction codes, reducing the impact of atmospheric turbulence on ground to satellite laser communication".Atmospheric turbulence in ground-to-satellite laser...
