The History of Laser
Laser has come to the world for decades, but the process of laser invention is less well-known by people. In fact, every significant invention is a collection of much wisdom with scientists’ sweat and labor. Laser is no exception.

Laser history of foreign countries
Laser is short for Light Amplification by Stimulated Emission of Radiation. Einstein first put forward the concept of the stimulated radiation in 1916. And scientists invented the maser, which stands for Microwave Amplification by Stimulated Emission of Radiation in 1954. A maser is basically a microwave version of the laser. Microwaves are a form of electromagnetic radiation similar to, but shorter than, radio waves. And then in 1858 it was applied to optical frequency range by scientists Schawlow and Townes. So until 1960 Theodore Maiman established the first working laser.
Laser history of China
Our country has been attached great importance on laser technology from the start. Hosted by Wang Zhijiang, the first ruby laser was carried out successfully in
Extensive use of laser
Now, laser has become an important equipment of industry, communication, science and electronic entertainment. It marks the development of new technology revolution. All kinds of laser machines have been launched sequentially. Such as laser marking machine, laser cutting machines, laser welding machines, laser micro processing, etc.

The prospect of the laser
Laser has the characteristics of good brightness, monochromaticity, coherence and penetrability. Since the beginning of laser, it's not hard to predict that its potential foreground is promising. Compared with electronics and aviation, although it is in the early stages of laser development, people should be very optimistic about the future of laser development.
