The initial Chinese name of laser is 'Laser' and 'LaceIt means to expand by stimulated emission of light.' The English full name of the laser has fully expressed the main process of manufacturing the laser. In 1964, according to the suggestion of the famous Chinese scientist Qian Xuesen, the light stimulated emission was renamed as laser.  Laser is another major invention of mankind since the 20th century, after atomic energy, computers, and semiconductors. It is called a fast knifeu0026rdquo;, a precise ruleru0026rdquo;, a bright lightu0026rdquo; and a strange laseru0026rdquo;. Its brightness is about 10 billion times that of sunlight. The principle of    laser was discovered by the famous American physicist Einstein as early as 1917, but it was not until 1960 that the laser was successfully manufactured for the first time. The laser came into being under the background of the urgent need of theoretical preparation and production practice. As soon as it came out, it achieved extraordinary rapid development. The development of laser not only gave birth to the ancient optical science and optical technology, but also led to The emergence of a whole new industry. Laser enables people to effectively use advanced methods and means to obtain benefits and results, thereby promoting the development of productivity.
