In his state of the union address in March, putin introduced the latest development of several important strategic weapons. Putin said Russia has made significant progress in developing laser weapons, and not just in theory or design — the peresweet laser system was delivered to the Russian military in 2017, but he did not elaborate…

Physicists from the Max Planck institute for quantum optics, the university of Munich in Germany and the university of umoo in Sweden have for the first time used a plasma of relativistic electrons to generate isolated, high-intensity attosecond laser pulses, foreign media reported. When the density of electrons accelerates close to the speed of light,…

In a quantum chip, the phonon resonator coupled with superconducting bits is a key component for connecting and converting photoelectric signals and performing quantum logic operations. This kind of coherent phonon device has wide application value in many fields such as quantum information, nanomechanics and thermoelectric materials, supersensitive sensing, nondestructive testing and geological exploration. However,…

The origin and development of laser devices The light source needed for optical fiber communication should be the light source that can be modulated at high speed to carry large capacity information. Such as lasers and tubes. The so-called “modulation” is according to the information to be transmitted to change the intensity of light, etc.,…

The regions beyond the north and south poles of the earth are wrapped in layers of magnetic field lines, and the magnetic field lines in and out of the polar regions are almost vertical, becoming the window of the earth’s space to the space environment. China’s 35th Antarctic expedition is carrying a “super laser pointer”…

Lockheed Martin is working to upgrade its advanced aegis combat system to detect emerging threats such as hypersonic weapons and drones, defense magazine reported recently on its website. Aegis system is an anti-missile combat system that has been tested in real combat. It has since developed land-based versions and is increasingly being deployed in strategic…

Yue jiangfeng, a senior engineer and project chief at a military research institute, gave the following answer to a question posed by netizens: “will warships replace artillery with lasaer pointer guns in the future?” Shipborne laser gun is a new concept weapon which is still in the development stage. The laser cannon is supposed to…

A 5p-42 “eagle owl” laser vision jamming weapon station developed by the Russian state technology group’s “rosatom” holding company has been delivered to the Russian navy’s “gorshkov” missile frigate for final testing in January 2019, Russian media reported recently. The 5p-42 laser blinding weapon station is a small lasaer pointer weapon station that can suppress…

Russian national technology research at the university of Moscow’s national institute for the steel alloy with Russian aluminium company responsible for lightweight materials and technology research of cooperation of scientific research personnel, and use the new processing and manufacturing method to produce the heat resistant high strength alloy, the alloy can ensure that the structure…

According to foreign media reports, a team of researchers from Massachusetts institute of technology has created the purest laser in the world. The device is portable enough to be used in space. It produces a lasaer pointer beam that changes less over time than any other laser. Normally, temperature changes and other environmental factors cause…
