Atom, the earliest abstract ontological significance of philosophy. As a microscopic particle exists, atomic neither see nor touched, which gives them a glimmer of mystery and sense of distance. With the advancement of human knowledge, atom abstraction from becoming a scientific theory. An atom consists of a nucleus and some surrounding dense surrounding the nucleus of negatively charged electrons. Electron motion around the nucleus, releasing energy, so that the whole atoms formed integrally with the outside world, continue energy exchange with the outside world is formed, the entire atom is in motion, the movement of atoms is the blood of the atom. Around us, so a group of atoms, they are cold surface, but its heart is absolutely gentle, they are called cold atoms. Before saying cold atoms, we start to understand the corresponding heat under the cold cold What is an atom? What is the nature of heat? Learn more about what kind of cold atoms can be called atoms? Cold atoms is how to achieve?

Hot nature

Fiber laser is a laser cutting machine is the core component, in general, it has played a significant effect on the cutting laser cutting machine. When choosing laser cutting machine, fiber laser customers are very focused brand, even the life of the module integrated manner. Well, today on the high-energy 30000mw laser pointer to tell you about the fiber laser modules.

In June 25, 2016, China March seven rocket first flew successfully, which is equipped with "Oberon 1" spacecraft, triggered a strong concern, although China official announced that its main task is to clean up the debris, but some analysts speculated the potential power the aircraft to anti satellite weapons, is a large aircraft prototype. Recently, the domestic and foreign media have reported that a number of countries in the world have turned their attention to the development in the field of space research in space, the use of weapons, in order to obtain the advantage of burning laserweapons is one of them.

President of the Russian Academy of Geopolitical Problems Konstantin Siv Cove on Wednesday in an interview with RIA Novosti interview that if the use of laser weapons in space will become more effective, but actual samples developed laser weapons also need to combat decades. Earlier, the chairman of the Russian Fund for future research Andrei Grigoryev told RIA Novosti interview, he noted that the development of 30000mw laser pointer weapons and beam weapons is very difficult, and there seems only just begun.

Daily life, a lot of news such as rising oil prices, energy crisis, global climate change will cause us to panic for the future. The current consensus is that we need to reduce dependence on oil in favor of clean energy, avoiding harm to our planet. This view is the people and governments around the world wide support, even in the United States. Scientists in various countries around the world are looking for alternative sources of energy, such as renewable energy sources like wind, biofuels and solar energy.

In mid-century, Bell Labs invented the "Bell of solar cells," but its high cost limited the development of solar cell industry, even after 55 years since then, solar photovoltaic power generation in the global grid accounted for only about 0.04% . However, the situation has changed in recent years, from flat panel display and semiconductor industries burning laser processing technology derived from the solar industry, there has been explosive growth.

To Avoid the Red Sea Looking For Laser Technology Research and Development of Blue Ocean

China green laser pointer industry develops very fast, we have new enterprises, industry mergers shuffle intensified, and a large part of the enterprise in some relatively low technological content of products competition, competition is more and more intense. One day, the laser industry, I'm afraid, will be like many traditional industries, industry saturation, overproduction. In order to survive, among peers irrational, make price war greatly, with "jump floor price", "cut throat price" desperately trying to win the market, make the market become economists say market of "the Red Sea." Laser light has felt this threat. For example, laser welding laser welding machine, laser welding, 2 years from 200 thousand yuan down to 60 thousand yuan, the profit is completely out of the. Ming radium laser to want to build a corporate brand, to create a hundred years old, must rely on the progress of technology research and development, make oneself out of the competition in the Red Sea, and constantly to fewer competitors of the blue ocean market.

In 2012, the company's main direction of 500mw green laser cutting laser cutting machine laser cutting machine. This equipment in addition to different technical requirements, capital investment, the project on the threshold is very high. Therefore, this field is generally small business is expected to be. Be able to on the project, the company has a considerable strength of both technology and capital. Relatively speaking, this area is a small competitive strength of the blue ocean market.

Laser Shocking Peening Technology

Laser shocking peening technology, different in 30000mw laser pointer cladding, laser alloying with high melting temperature and latent heat of solidification process of surface modification method is by using strong pulsed laser induced plasma detonation wave on the surface of the metal material implementation of ultra high strain, high strain rate deformation of cold processing technology. When the high power density, short pulse laser by constraint transparent layer in the energy of the metal surface of the coated absorbing coating, coating absorbs laser energy is gasified quickly and formed a dense plasma with high temperature and pressure, the plasma absorption to 20000mw laser pen energy rises rapidly temperature expansion, and then an explosion forming high intensity shock wave on the surface of the metal, the material plastic deformation and the surface generated parallel to tensile stress on the surface of the material; after the end of the laser, due to the impact zone of the surrounding material reaction, so that the surface material to obtain high residual compressive stress. The residual compressive stress can reduce the tensile stress level and crack closure effect, which can effectively improve the strength, wear resistance and fatigue life of the material. Burning lasershocking processing technology is suitable for steel, titanium alloy, aluminum alloy and other materials, and it is widely used in the field of aviation and advanced manufacturing.

The laser shocking processing of ultrafine grained high carbon steel obtained by the equal channel angular extrusion of a university in China has been carried out, which further improves the performance of the material. They used materials for steel commercial Fe-0.8C. After four equal channel angular extrusion deformation; laser shock processing laser spot diameter is 3mm, the laser wavelength of 1064 nm, pulse width of 10ns and repetition frequency for 1h, the laser pulse energy for 6J, overlap rate was 50%. The aluminum foil with thickness of 0.1mm is pasted on the polished surface of the sample, as the absorbing layer of laser energy, and the water flow is controlled by the flowing water as the constraint layer in the 2000mw green laser shock. The back of the sample is coated with a layer of silicon oil as a wave absorbing layer to prevent the shock wave from reflecting back from the back of the specimen, forming a tensile wave and causing damage to the sample.
