The competitive price helps the laser pointer

 The competitive price helps the laser pointer company take up more market.
But if one uses a laser to light the photo will appear in front realistic three-dimensional scene. Even more amazing is to observe from different angles, you can see different aspects of the

original object. Also, if you do not accidentally hologram broken in pieces, it does not matter. Free to pick one of a small piece of debris, observed the same way, the original subject is still

intact displayed. The principle is the use of holographic optical interference principle, the use of two-beam interference of light to record information on the subject. This theory has long been

raised, but it requires only a laser to achieve a high degree of monochromaticity. Therefore, only after the birth of people in the laser was able to achieve that dream. The price of this kind of

laser pointer is more competitive.
Another area of laser medicine flourish. It is not only in surgery can be used as a laser knife, and in ophthalmology, dentistry, dermatology and cosmetic aspects are unique applications. The

beauty of laser knife cutting at the same time that it was burning, which happens to be closed vessel to prevent the bleeding, also reduces the risk of infection. Painless laser drilling of teeth

and tooth decay to make people terrified of the dental surgery the previous great sense of ease. Compared to previous mechanical drilling, laser drilling is not only not have a lot of friction

heat, and it just evaporated corrosion at the black teeth, healthy tooth tissue does not have an impact, so pain will be greatly reduced. The price of laser pointer provided by the laser pointer

company is very attractive.Begin construction in Maiman's ruby laser before he, it was by no means assert that the ruby laser is to create good material, and Filo also support this

view. This makes a lot of people stop to make a ruby laser with a try, but they suspect that this argument Maiman. To this end, he spent a year and research devoted to measuring the nature of ruby,

finally found the basis of the above assertion is based is wrong, and the ruby laser does is to create good material. Since he started the construction of the world's first laser.This condition is called "inversion." How to achieve population inversion state? This requires the use of active medium.
