The original Chinese name of laser is called "laser", "Les" is its English transliteration of the name of LASER, is an acronym from the English Light Amplification by Stimulated Emission of Radiation each word consisting of the first letter, meaning "through Light Amplification by Stimulated Emission. " Laser full name in English is completely expresses the main process of manufacturing the laser. The principle of laser early in 1916 has been the name of the American physicist Albert Einstein discovered, but not until 1960 was only the first successful laser manufacturing. According to China in 1964, the famous scientist Qian proposed that "light by stimulated emission" renamed "laser." Laser since the 20th century, following the atomic energy, computers, semiconductors, another major invention of mankind, is known as "the fastest knife," "the most accurate ruler", "the brightest light" and "bizarre laser." China's laser processing industry has been exponential growth, China has become central China, the Pearl River Delta, Yangtze River Delta, Bohai Sea with four laser industry, in 2008 the national laser industry sales to 80 million, there are 21 provinces and regions of production and sales of laser equipment, a perennial stereotypes production and sales, and formed a certain scale units have about 300, became one of the most active emerging industries. State Science and Technology commissioned the China Optics and Optoelectronics Industry Association statistics show that 1991--1995 total sales of China's laser industry was 125 billion yuan, 69 times the 1995 annual sales in 1990, the average annual growth rate of 2.3 times, far far exceeding the growth rate abroad. Where the largest optical storage sales, of 109 million, five-year total exports of CD machine 21.2 million units, worth $ 820 million, followed by the distance, collimation, 780 million yuan; third is the laser medical equipment 250,000,000 yuan, fourth laser processing equipment 210,000,000 yuan.  At present, the country engaged in the production of lasers and laser application equipment more than 500 units around which the production of laser has more than 380 audio and video equipment, production of other laser equipment has more than 150 national Laser Engineering Technology Research Center has four various types of laser processing station has more than 120, and is developing rapidly.
