Recently, we have seen the number of cases in which the green light laser pointer grows glare Airline pilots: There are nearly 1,500 such incidents per year, reported by the British Journal of Ophthalmology. The periodic state is even when the laser beam has damaged the driver's retina. However, the doctor said that this situation is extremely rare. The large distance between the planes of the ground provides a sufficient dispersion of the beam and reduces the energy of the light absorbed by the eye.
While technological advances have allowed the improvement of laser power by improving their own strength, they can worsen to a person at distances of several meters. The pointer, the laser pen and the keychain usually emit a red light beam whose energy does not exceed one milliwatt (MW), which is not enough to hurt the eyes. However, recently, can be increased to 300 milliwatts, so it should be used correctly.The online store offers a more powerful laser indicator with an efficiency of 1000 mW or 6000 mW. Like this device can go to the farther place. Experts believe that these lasers are already very mature, very popular, worth buying.
You can access the high professional performance of a burning blue laser pointer. It can make your spot size different because of its optical components. These lasers have variable focal lengths. Most of the time they come with a lithium battery and a charger that includes 2400 mAh. They have a system security key. By browsing, you will find various styles. They are available at 150 mW 50 mW power. Other powers of 200 mW available upon request. You can find 240MW blue laser pointer, new, new at low price!
You do not have to worry about the CE mark because they understand the instructions and use and sale of the EU. The blue laser pointer is much more powerful (about 200 times) than the red laser pointer. The eyes are much more sensitive to the green; in addition, the laser pointer is illuminated with a red pointer and so on. With a variety of in the dark (3-4 km), the pointer is ideal for astronomy. The wavelength 100MW laser indicator is 532nm (blue), with continuous emission of radiation; therefore, its light can be seen from the air in the dark or low light.
According to the physicist's network recently reported, purely diamond lattice structures consist entirely of carbon atoms and do not interact with the magnetic field. The lattice nitrogen defects of the artificial diamond voids are called when the carbon network forms nitrogen vacancies in the nitrogen atom, and the vacant electrons can interact with the magnetic field, and the magnetic field is extremely sensitive, with only one twentieth strongest laser pointer size. The microchip diamond contains a vacancy of one trillion nitrogen vacancies that can be made for each magnetic field probe. Scientists want to create an effective mobile magnetometer based on the question of how to put all the tests. The detection of nitrogen vacancies using laser radiation, which absorbs photons and then emits light, emits light intensity, and carries out espace.Les researchers' field calculations of the state information into the laser crystal angle from each facet as a billiards billiards The table reflects the laser beam continuously rotating on both sides of the crystal in the bounce until all the energy is completely absorbed. "Thanks to the total mix of more than one meter closer."
Massachusetts Institute of Technology Assistant Professor Jamison Electric Training Center and IT Deke UK Grund said, "You put a long diamond-shaped sensor connected to a few millimeters within a few millimeters." Therefore, the energy-saving chip green laser 300MW pump in the past Almost a thousand times. "We can use almost all of the detection pump nitrogen empty light".
When the photon strikes the electrons in the nitrogen vacancy, it will hit in a higher energy state when the electrons return to its original energy state, which would be like any other release of extra energy as photons. And the magnetic field will reverse the magnetic direction (or spin direction) of the electrons, increasing the energy difference between the two energy states. The higher the magnetic field, the more it will return to the electron spin, changing the brightness of the luminescent vacancy. Because of the geometric shape of the vacancy nitrogen lattice, the photon will fill the four shots of the angle. Next to each lens discharge can collect 20% of the emitted light, gathered in the photodetector, producing experts who have enough injuries to detect fiable.Si, who can always consult the eye. Many professionals are in the eye care experience. Blue laser pointer beamsArticle submission, pen and key chain available online and retail store. If you do not have much knowledge, you can see a lot of photos and videos to learn how and blue lasers. A 1600mw laser flashlight can be a suitable gift! Compare prices and keep the best of the article. You just love your new laser. Green laser pen more and more use of green laser pen astronomy enthusiasts show in public places such as stars night sky; other parallel with their telescope with it as a viewfinder. So, but in recent weeks these tools have been questioned in the heart of the questioning of its harm to aviation civile.Catherine Dumas has purchased a laser puissantadopter an amendment to the bill Loppsi 2 (positioning with the planning of the law of national security). It stipulates that "the fact that the purchase, the use of laser equipment, does not target the use of a higher level of 2 for 6 months imprisonment and a fine of 7500 euros. The same penalty is the fact that the laser pen is produced, imported, to provide To the free or expensive, reserved for sale or free distribution, offer for sale, sale or free distribution of these materials. "3 lasers, using astronomers" in 600 complaints recorded in less than a year of astronomy laser lasers against laser In the Orly and De Gaulle approach, "Senator Catherine Dammars said. The case was taken seriously: August 31, 2010, a 20-year-old man was sentenced to a probation that has pointed out a 6-month laser pointer on landing at the cockpit at 3 aircraft in Orly (Marne Valley province). "Landing is a critical stage and there is less than this crash," said Maxime Maca, a lawyer in law.
When looking for new business administration new things, it's helpful to consider the applications that all applications might initially create.
In fact, in recent years, blue laser pointer have been used as office gifts for most employees and served them.

Universal fiber polarizer has a short board, Xi'an Institute of Optics and Fine Mechanics, Chinese Academy of Sciences Institute research team femtosecond pulse laser-induced change in refractive index silica fiber cladding, the invention of the femtosecond green laser pointer lithography fiber polarizer a new structure has been recently won the national invention patents.Fiber polarizer is widely used in fiber lasers, fiber optic sensors and measurement field, the traditional fiber polarizer are the following: a polarizer type fiber polarizer, D-type fiber polarizer, polarizers and other fused taper.
Among them, the spatial structure of the polarization mirror optics fiber polarizer involved more, not easy to adjust.
D-type fiber polarizer due to the precision grinding and fiber coating is very high, so that the finished lower efficiency.
Fused fiber polarizer is an optical fiber at a high temperature molten state and then pull the cone shaped crystal to generate polarization anisotropy generated effects, the bandwidth is generally about 30nm.Xi'an Institute of Optics and Fine Mechanics Institute Transient Room Cheng Guanghua, Zhao Wei, Quartz for technical problems of conventional fiber polarizer present in-depth research, the invention of the femtosecond laser lithography fiber polarizer a new structure: the use of flying second pulse laser induced silica fiber cladding refractive index changes in the fiber core having generated around the same polarization characteristics of the light guide nanometer periodic grating.
In the fiber core evanescent wave transmitted light is modulated by the surrounding nano stripes, horizontal and vertical polarization components of different scattering properties perpendicular to the plane of vibration nano-scattering component is very obvious that this is a large number of scattered polarization state, parallel to the plane of Nano the polarization state of low loss, after a certain length of the transmission, and ultimately achieve higher extinction ratio (> 20db).
Since the polarization insensitive wavelength scattering characteristics and the relationship between the nano-grating, nano-stripes for different wavelengths have high polarization extinction ratio.
Les lasers sont devenus la norme pour presque tous les films de science-fiction.
Le pointeur laser nous donne toujours un sentiment éblouissant et mystérieux.En réalité, le laser n’est pas mystérieux, son principe le plus simple consiste à ingérer de la lumière dans une cavité composée de miroirs à deux côtés: lorsque le faisceau se réfléchit, la lumière est renforcée dans la cavité et la longueur d’onde devient unique.
Un petit trou apparaît, c'est le pointeur laser vert que nous voyons souvent le jour même.
Que dites-vous de la cavité résonnante?
Je ne comprends pas, mais dans cette vidéo, vous saurez que la plus ancienne cavité de résonance utilisée par l’inventeur laser était un bâtonnet de rubis, dont les extrémités étaient polies et lisses, plaquées d’argent sous forme de miroir, puis placées dans un tube.
Cela fait le premier laser dans l'histoire!
