Although the laser from the date of birth, by the military's widespread attention, especially in the field of strategic anti missile. But because of the difficulties of the atmosphere, the optical attenuation, the heat dissipation and the target guidance, the development speed of the strategic high power laser pointer weapon is very slow. But since twenty-first Century, the U.S. military once again starting to focus on the development of high power solid state laser, which is used to perform short-range air defense and Antimissile Defence, warship tactical mission, and the U.S. military said a mysterious weapon again ahead of competitors.

According to the British "Daily Mail" recently reported that the world's largest manufacturer of Northrop Grumman radar is working with the US military, the next generation of supersonic fighters to develop new laser pointer weapons, the power of abnormal terror. The weapon system, known as the directional energy system, is primarily used for self-protection of fighters and is placed in a special installation. US military research laboratory revealed that this system is expected to be installed in 2019 in the US supersonic fighter, into the test phase.

Before the sacrifice of the "Golden Phoenix" Yu Xu, senior researcher at the Chinese Academy of Sciences in Ningbo, Zhang Wenwu has been thinking, what is the problem caused the aircraft accident. As the Ningbo Institute of advanced manufacturing technology research institute deputy director, in recent years, Zhang Wenwu led the research team, has been in the key technology of intelligent burning laser pointer processing research, and the core component of this technology will be used in the next generation of Chinese engine manufacturing.

This year, Zhang Wenwu made the team "turbine blade complex" Research on key technology of special film hole intelligent laser processing project, the National Natural Science Foundation of Zhejiang - the integration of the two support fund, provides the possibility for the cure of aero engine core components.

The day before the researcher Dr. Zheng Mingbin College of medicine of Guangdong Medical University and Chinese Academy of Sciences, Shenzhen Institute of advanced technology Cai Lintao cooperation, in the homologous drug loaded nano to make new breakthroughs and accurate visualization for cancer treatment, the development of "new treatment of cancer, cancer research recently in the field of Nanotechnology" ACS Nano "top journals published.

Zheng Mingbin, the research team constructed the encapsulation of indocyanine green (ICG) - cancer cell membrane biomimetic polymer nanoparticles (ICNPs), and applied to the diagnosis and treatment of breast cancer by homologous MCF-7. The expression of adhesion molecules on the membrane of cancer cells, such as epithelial cell adhesion molecules, N-cadherin, galectin, through receptor - ligand binding form to cancer cells each other "navigation" and "anchor". Nano particles wear vest to cancer cell adhesion molecule recognition MCF-7 adhesion cancer cell membrane, to avoid the effect of chemical modification to the target complex and potentially uncontrollable factors.

NASA scientists looking for life on Mars, the biggest concern is that if one day found a trace of life, the results came back to see the pollution brought about by the Earth. Now with an upgraded version of the lidar LIDAR, both to solve the concerns of scientists, but also to explore more efficient.

This tool is called the Bio-Indicator Lidar Instrument (BILI). Branimir Blagojevic is now a technical expert at the NASA Goddard Space Flight Center, which originally served the company that pioneered the development of the device. At NASA, Blagojevic uses his experience and skills to turn this technology into a working prototype, proving that the instruments used to detect biological hazards in public places can also be used to detect organic matter on Mars. LIDAR works much like a radar, but it uses a 2000mw laser pointer to measure distances and determine the composition of airborne particles.

The electron is a subatomic particle, belonging to a lepton. For a long time, because of its small quality (9.1x10-31 kg), fast (a week around the atomic nucleus only need 1.8x10^-16 seconds), although the use of a wide range, it is difficult to observe. In February 2008, a number of scientists from Sweden for the first time to take a single video recording, to achieve a historic breakthrough. However, want to shoot electronic solid inside, because the electronic large number and complicated environment is more difficult. Scientists have not found any direct observation for a long time. Until a few days ago, from the Okinawa Institute of Science and Technology Graduate University scientists use their "femtosecond camera" succeeded for the first time to take the material internal electron trajectory, once again to achieve a breakthrough. Since Thompson was discovered in 1897, scientists have tried to describe the motion of the sub atomic particles in many ways. Electrons laser pointer 5mw are too small to move too fast, not to say the naked eye, or even an optical microscope. So, how to measure the movement of electrons, stumped generations of scientists. However, Institute of Science and Technology Graduate University Okinawa femtosecond spectroscopy laboratory, so that human beings to observe the electronic movement of the goal of a big step forward.

For more than 30 years, the power and performance of carbon dioxide (CO2) lasers has appeared to be at an extreme level, and most consumers buy CO2 laser equipment in the range of 4-5 kW (and occasionally 6 kW). It took about 15 years to make 3kW CO2 blue laser pointer sales become common, and then spent five years to make 4kW products become the mainstream choice for end users. In fact, higher power CO2 lasers (6kW and above) have been available for many years, dating back to the 1990s. Although sales of high-power CO2 lasers have increased slightly in the 21st century, they have never been able to match sales of products that are close to 4-5kW.

St Petersburg State Technical University, Department of Physics, Nanotechnology and Electronics, Moscow State Institute of Electronic Science and Technology scientists jointly developed optical radiator, which can improve the accuracy of laser 5000mw radar 10 times. This increase in speed can be used to scan shorter optical pulses in modern radiators, the St. Petersburg State Technical University Press Center reported. An optical radar is a device consisting of three main components for determining the distance: a radiator that transmits an optical signal (usually a laser beam), a receiver that captures the reflected signals of various objects around the radar, and a receiver which distinguishes it according to a characteristic difference, The time interval between the delayed signals is constructed around the terrain image data processing system.

Therefore, the shorter the pulse duration and the higher the power, the higher the range and accuracy of the radar. "We have reduced the pulse duration while maintaining the pulse power, which greatly improves the range and accuracy of the radar, which requires the development of a new element matrix and the use of a completely new electronic device" "Said Alexei Filimonov, director of the Department of Electronics.

Laser cured red blood to restore the health of the skin, friends are aware that the impact of red blood on the appearance of a very large, smart woman can not tolerate the slightest flaw on the face. What's more, it is an ugly red blood? Here are some ways to treat red blood. Hope to provide some help to my friends.

The US Navy is likely to revamp its carrier's size, shape, technology configuration and mission characteristics after a careful study of the emerging global threat environment, US Navy officials have revealed, the US National Interests website reported Monday. Speaking of China's future laser pointer 1mw aircraft carrier construction will also consider these innovative factors, the military expert Li Jie in an exclusive interview with the People's Network, said China's development of aircraft carriers is taking a gradual path, has entered the large aircraft carrier national sequence, the future fixed-wing ship Aircraft performance and unmanned platform applications will continue to increase.

Reported that, although the US aircraft carrier specific innovation program has not yet announced, but the future carrier may be equipped with more advanced sensors and ship protection equipment. For the defense of enemy firepower, the future speed of the aircraft carrier will be faster, more controllable. At the same time, the aircraft carrier will be improved to equip more unmanned aerial vehicles. Analysts said the US Navy aircraft carrier performance is designed to enable it to combat in highly dangerous environments.
