(Jihai the twelfth lunar month 20), January 18, 1960, the United States developed the ruby ​​laser. The ruby ​​laser Maiman developed the success of the world's first practical application,




1960. It marked the birth of the laser technology. (L $ dj��.c��m) In 1960 January 18, 2010 (on www.TodayOnHistory.com) California, Hughes Laboratory Theodore Maiman developed the world's first ruby laser. Since then, the laser has been exceptionally rapid development of science and technology.
laser known as known as magical light. Now, you just a little attention, you will find laser on around us: sounding CD player music constantly echoed between the buildings; laserdisc players quietly into the household; the mall merchandise paste laser anti-counterfeit mark; The laser phototypesetting swept all the newspapers and magazines. We are separated by thousands of miles can talk with friends and relatives, but also the credit of the laser, because it is the optical fiber to transmit laser. The laser engraving meticulous, extremely accurate, high-strength materials such as steel, crystal carving, widely used in industrial marking, laser forming, gift signage.
Maiman, American physicist. (History cn) In 1960, May 15, 2010, in a research laboratory of Hughes, the young American physicist Maiman is undertaking an important experiment. His experimental apparatus an artificial ruby ​​rod. Suddenly, the bouquet of crimson light emitted from the device, and its brightness is four times the surface of the sun! Light this is a completely new type of light, scientists eager for many years but nature does not exist, it is named Laser stimulated emission light amplification large abbreviation, which is laser. Generating a laser device is called a laser. The advent of the laser and the laser is known as one of the most significant scientific discoveries of the 20th century.
