The parameter of laser pointer can not be revised easily

 Therefore, the laser processing technology for Germany, higher than any previous period. The parameter of laser pointer can not be revised easily.
Light source for materials processing, German companies  accounted

for almost 40% of the world market, in the lead. At the same forward, also signed orders for 1544 units lasers contracts worth 177 million marks. Laser system in 1994, the turnover has increased

substantially completed the production amount of 860 systems valued at 235 million marks, the number of units grew 51%, sales growth of 17%. At the same time, the system also signed 937 contracts

worth 249 million marks , these contracts and the amount of production in 1995, close to forecast.
On the application of laser in ophthalmology is the most amazing. Laser welding can be torn off the retina, leaking blood vessels closed, completely destroyed the eyes of jelly floating in the

liquid in the tiny grains of sand. The advantage of laser surgery can be done without cutting the eye surgery, and greatly ease the pain of surgery. --- For the current incurable

cancer, the laser also provides an effective weapon. On the one hand, the laser can be used as a laser cutter to remove the tumor; the other hand, in the early diagnosis of cancer are also

effective. The success of this series of powerful laser Bell Labs into the study, and its financial and human resources to promote the research and rapid progress of the work.

Since 1960, the family has a rapid growth of the laser. There are various different shapes of a variety of lasers of different sizes can produce different power, different wavelengths of laser

light. These include laser range from infrared to ultraviolet and even X-rays of all regions. There are two ways to classify the laser. One is the state of matter from the active medium of faceted

classification. This can be divided into gas, liquid, solid and semiconductor lasers. The customer is very satisfied with the agreement of laser pointer .
Various types of lasers have their own characteristics. Strong monochromatic laser gas such as helium - neon laser monochromatic light source is higher than the average 100 million times, and a

wide range of gas laser working substance, it can produce many different laser frequencies. However, due to low gas density, the laser output power corresponding smaller; solid-state lasers, by

contrast, high energy, high output power, but the work material types is relatively small and poor color; the liquid laser is the most important feature of the laser wavelength can continuous

change within a certain range.
