In fact, laser weapons are a kind of directed energy weapons. According to different operational purposes, it can be divided into two categories: tactical laser weapons and strategic laser weapons. Among them, tactical laser weapons use laser as energy to directly kill enemy personnel, tanks and planes like conventional weapons, and the strike distance is…

The all-optical scheme to achieve particle acceleration has attracted a lot of attention in the past two decades due to its potential advantages in significantly reducing the size and cost of accelerators. The plasma generated by the laser pointer can maintain a very high acceleration gradient, thereby enabling effective acceleration of charged particles. In particular, in recent…

Loma has recently completed the design, development, and verification of the Army’s 60-kilowatt laser weapon system under the support of the Ministry of Defense’s “Reliable Electric Laser Initiative” project. This laser weapon system is composed of multiple fiber laser pointer. The output power reached 58 kilowatts in the March test. It is planned to be delivered…

Scientists at the Swiss Federal Institute of Technology in Zurich used a new method to generate highly stable offset frequency comb pairs from a single integrated free-running semiconductor stacked laser. They use birefringent crystals in the laser cavity, which can tune the beam and frequency comb offset simply by changing the crystal thickness. The team…

Ultra-high-speed imaging technology provides researchers with the best perspective to observe the atomic world. Molecules and atoms jump and spin in space, seeming to dance seriously, they continue to twist until a molecular chain is broken, and the other segment happens to “click” into place. These imaginative pictures have been staged in the minds of…

In the development of the Shenguang II device, the development of the laser light path automatic collimation system has been highly valued. After learning and absorbing the mature experience at home and abroad, Chen Qinghao is responsible for the collimation subject, and in accordance with the requirements of the Shenguang II device, innovated “dynamic correction…

Most non-fiber lasers must use a large water-cooled machine for water cooling, which requires regular daily maintenance. The deionized filter element, particle filter and deionized water must be replaced regularly (usually every six months) to prevent water pollution. If the quality of the cooling water cannot be guaranteed and maintained, the laser pointer efficiency will be reduced,…

It is reported that scientists from the Tokyo Institute of Technology in Japan and the Kyoto University Institute of Material-Cell Integration Sciences used femtosecond visible light and terahertz pulses as external perturbations to study the second harmonic generation effect of light-excited bismuth oxide. This study highlights the importance of ion orbital excitation; this study is…

Traditional high-power lasers are bulky and require equipment that can be used on portable platforms. Engineers at the University of Texas at Arlington in Arlington are working to develop a semiconductor laser that solves these problems. The high-energy laser pointer joint technical office launched a five-year, multi-disciplinary research project with an investment of 3 million US dollars…

Traditional cleaning industrial equipment has a variety of cleaning methods, mostly using chemical agents and mechanical methods for cleaning. Nowadays, the requirements of environmental protection regulations are becoming more and more strict, and people’s awareness of environmental protection and safety is increasing. The types of chemicals that can be used in industrial production cleaning will…
