Carbon dioxide green laser is a laser. The main material is carbon dioxide molecules. It can be expressed in a variety of energy states depending on its vibration and rotation form. The mixed green laser gas is shown in Figure 1 in the basic energy net carbon dioxide is a low-pressure gas caused by electronic release (usually 30-50 support) formation (electric plasma pulp). Such as Maxwell – Pohl Seidman distribution law said, in plasma, showing a variety of molecular excited state. Some will show a high green laser energy state (00o1) and its performance for asymmetric swing.
And when the hollow wall green laser collision or natural dissemination, such molecules can also loss of energy by accident. Through natural shine this energy will drop to symmetrical swing form (10o0) and emit photons may propagate to any direction (a beam green laser wavelength of 10.6 mu m). Occasionally, a photon along this the optical axis of the cavity downward green laser propagation will also resonate in the mirror swing.
The waste heat rejection mode has a great influence on the design of green laser system. In principle, there are two possible ways. The first way is the automatic processing of natural diffusion heat to tube wall based on the principle of operation is sealed and the slow axis flow green laser. second is based on air forced convection, the principle of operation is fast axial flow green laser. in general, there are five main types of carbon dioxide laser.
Seal or no flow of carbon dioxide green laser usually used to do laser beam deflection mark. Its discharge tube is completely sealed. The laser beam quality is very good. But in most cases the discharge can be for the old and the new can be re filled with air so easy maintenance. There is no need to use the gas supply system of separation type you only need to connect. Do less in green laser head. So it is compact and lightweight.
This is for IPG is important because green laser only IPG have the high power fiber lasers. Similarly, we found that the pulse green laser marking and engraving OEM customers to purchase more high power, it also enhances our competitiveness from the use of.OEM output power of 2 kW green laser to make use of 4 kW, 6 and kW 10 kW green laser is a continuing trend in the fourth quarter. We also expect the 12 kW fiber laser can demand has increased significantly.
There are special parts of Europe green laser demand driven strong growth for the core quarterly sales new record cutting applications encouraged. Our OEM customers green laser tend to improve their cutting power cutting system to improve the processing speed and cutting thickness, the third quarter sales, reflecting the demand at the green laser beginning of the year compared to the downturn, our core application needs there are signs of rebound rebound. Because in Asia and North America.
Compared green laser with the same period last year, widely used including automotive, aviation, oil, natural gas, nuclear power, railway, construction, heavy industry, green laser battery welding and cladding applications continue to be IPG business highlights. Welding application of sustained growth is because our fiber lasers significantly better beam quality, green laser faster welding speed the lower cost of equipment, and more suitable for the automation and process control.
As we continue green laser to develop new welding and cladding process and application of the laser so we can in our expected sales growth in the field. We have very many orders reserves in this core application. Green laser welding is the biggest advantage of processing new advanced materials such as high-strength steel, Aluminum Alloy, green laser titanium alloy and other alloy and a variety of metal complexes.

Beam shaping not only allows users to create better products, green laser but also help them to effectively control some challenging applications. With the development of optical components and industrial laser processing, green laser beam shaping technique also allows the user to move forward in a very flexible way, by adjusting the beam shape to meet the the specific application needs. As the best condition optimization of material processing, in the past few years, TRUMPF has fully mastered the green laser formation of arbitrary beam on the workpiece, thereby improving material processing.
Beam shaping technology of wave optics design green laser optimization and of the fused quartz transmission element manufacturing method based on improved. Beam shaping technique is not only suitable for ultrafast (i.e. ultrashort pulse laser), is also suitable for multi kilowatt CW (CW)green laser beam shaping technology. In with high efficiency and power handling capacity at the same time, can also provide beam plastic flexible methods for different applications, green laser from basic mode to multimode, continuous emission from ultra fast, and can cover a wide spectral range.
In addition to adjust the beam intensity, but also can produce multiple spot. This method has certain cost advantages, because the technology of green laser products can use standard, which means that the green laser source can use standard (such as continuous conduction fiber laser) and standard, without any specific adjustment or modification.
The detector can also help doctors green laser identify brain cancer cells in the region, but only through the display of visual presentation. While the blue laser pointer new detector can convert audio signal of the signal, the doctor can “hear” cancer cells in the brain, the eyes focused on the resection site. Participate in research at Clyde University, Matthew Beck said. The new green laser technology can accurately guide the signal, let the doctor “all eyes focused on the operation”.
For cancer patients, cancer green laser cells are not cleaned will relapse and metastasis and resection of left hidden trouble, healthy cells, nerve function and damage, green laser causing serious side effects. The next step, they will strive for the early clinical trials of laser detector, to help doctors to remove cancerous brain cells, but not the removal of the healthy cells blue laser pointer.
Do not think that this is a kind of invisible glasses, is not new. It consists of biophile inert material, green laser the body will not be excluded, it will not degenerate life loss, corrected visual acuity, as long as the small pieces in your eyes, green laser and then rinsed with saline. After 10 seconds, the bionic crystal will spread your whole eyeball.
Light is an electromagnetic wave green lase with peaks and troughs, all composed of a bunch of ordinary light laser has the same phase, so synchronous peak or trough to arrive. While bending beams of different, different light green laser waves having different phase, so it shows a spiral shape in the road, this kind of spiral curved beam and encryption almost no information transmission capacity constraints, communication become especially green laser suited for satellite communication.
Also related research reports, tooth preparation green laser of erbium green laser and general dental turbine, green laser has no vibration, no preparation, no anesthetic or reducing the use of these advantages, can reduce the pain of patients, record the green laser tester of erbium green laser cavity preparation conditions using scanning electron microscope and the temperature is especially suitable for the Department of Stomatology treatment in children.Beloica and Al-Batayneh in vitro, the results show that the green laser can remove the tooth surface smear layer effectively, reduce crack.
Root canal therapy is through the mechanical green laser removal method of green laser chemical drugs in the root canal infection, disinfection of root canal and root canal unobstructed, finally filling root canal filling agent to seal green laser apical. Bacteria and their products play an important role in the occurrence and development of the endodontic disease, root canal therapy objective clear root tube pathogenic factors, promote periapical green laser disease.
In the depth of dentinal green laser tubules reduced bacteria were no statistically significant difference, but group A bacteria reduction rate green laser in each layer were slightly higher than the C group, which may be related to the mode of action of Er:YAG green laser in the A group, the green laser irradiation can promote it to stir the sodium hypochlorite dentinal tubules penetrate into deep, deep to kill that sweet Tian bacteria. The photoa coustic guided photon green laser .
Laser and NiTi devices combined removal of the smear green laser layer of root canal and the protection degree is better than green laser group and NiTi group were better than the instruments, and step back technique.Kokuzawa canal green laser preparation research of Er:YAG laser root also proved the effectiveness of Er:YAG green laser removal of the smear layer and the opening degree of dentinal tubules. Thus, the laser in the root canal have the advantage of preparation.
You’re wantonly trying to get the green laser pilot to crash it and kill between 50-800 people. In my opinion, that sentence was a bit low. Attempted mass homicide should get you locked up for much longer. Because mass homicide is what you’re effectively trying to do when you point a green laser at an aircraft. You’re wantonly trying to get the pilot to crash it and kill between 50-800 people.
Green laser has two important components: first, the need to enlarge the light of the media; secondly, the light will remain in the structure of the medium.The feedback mechanism of the random green laser is based on the random scattering, and its internal microstructure can also emit light, but the light scattering direction is different.
From Italy Rome University and Munich University of technology in Germany’s international team, created the first green laser based on controllable random cellulose paper, the successful use of the light scattering effect of TiO2 ceramic. The results are published in the green laser issue of “advanced optical materials journal, describes the scientific research personnel” will be applied in random biological structure green laser template technology. ”
Sunscreen is a strong light scattering effect of TiO2 based on random green laser also use this effect. The research team believes that the long fiber filter can form a stable structure, so it can be used as the template structure of random green laser.
