Laser technology and development
The development of modern information technology and the information industry has become a hot spot of increasing attention at home and abroad in this century. my country's laser technology scientific research and industrial development are very rapid, and many units have been established, such as Optics Valley, Optoelectronic Industrial Park, Scientific Research and Production Group Corporation. Not only does it supply domestic demand and has been exported abroad, but the domestic market is full of products and trade is booming. The emergence of these intersecting technologies and new disciplines has greatly promoted the development of traditional industries and emerging industries. Cheng Wen learned that a few days ago, she complained that a little girl in her family pulled a 100mw high power laser pointer to get red spots everywhere, and it would arouse interest. In this medium, the population can be reversed to create the necessary conditions for obtaining laser light. Obviously, the existence of metastable energy levels is very beneficial to the realization of population inversion world. There are nearly a thousand kinds of working media, and the laser wavelengths that can be generated include far-infrared from vacuum ultraviolet to a very wide range.

Parents don’t pay attention to girls who have fun seeing a person. What exactly is the red dot in the pen? Accompanied by the child's curiosity, he lost control for a while and placed the laser pointer on his opened eyes. The red shot straight in the eyes without hindrance. The girl with the dazzling green laser pointer put it away, but for a few seconds. It may have been those few seconds that caused the girl to appear under the vision of "Shadow" and did not disappear for a long time. In 1994, the American Optoelectronics Industry Development Association made statistics on the world laser-optoelectronics market in 1993, with a total output value of 75 billion U.S. dollars; the American Optoelectronics Industry Development Association referred to displays, optical storage, optical communications and hard copy as optoelectronic technology industries. He also believes that Japan is currently the dominant player in this field, and Japan accounts for about 50% of the US$75 billion output value. Therefore, the United States believes that attention should be paid to the development of the optoelectronic technology industry so that the United States can occupy a larger share in this field. The following mainly introduces the development of laser processing and laser medical treatment in the United States.
