The word "laser" is the free translation of "LASER". LASER was originally a combination of Light amplification by stimulated emissi on of radiation. In China, it was translated into "Leeser", "Optical ejector", "Light-stimulated radiation amplifier" and so on. In 1964, Academician Qian Xuesen proposed to name it "laser", which not only reflected the scientific connotation of "stimulated radiation", but also showed that it is a very strong new light source. It is apt, expressive and concise, and is consistent with the scientific community in China. Identify and use it to this day.
Since the first laser was successfully developed in China in 1961, with the joint efforts of the national laser research, teaching, production and use units, China has formed a laser technology field with complete categories, advanced level and wide application, and achieved industrialization. It is gratifying to make progress and has made positive contributions to China's science and technology, national economy and national defense construction, and has won a place in the international arena.
China's laser processing equipment industry has also achieved rapid development in recent years to meet the growing market demand. According to the analysis data, China's laser processing equipment market reached US$3 billion in 2012. The market share of high-power equipment and small- and medium-power market respectively It is 46% and 54%.
In January 1987, the China Optical Industry Association was established, and later renamed the China Optical Optoelectronics Industry Association, which has a laser branch. According to the survey and statistics of China's laser industry in 1998, the country's major laser product production units are about 100, with 6,400 employees and per capita sales of 125,000 yuan, mainly distributed in Hubei, Beijing and Shanghai. China's laser industry increased from 100 million yuan in 1988 to 800 million yuan in 1998, with an average annual growth rate of 22.3%, and total sales in 10 years reached 4.12 billion yuan. In 1998, exports were 11.2 million US dollars, accounting for 11.6% of the total value.
At present, China has five national laser technology research centers and more than 10 laser research institutions, 21 provinces, municipalities and autonomous regions and more than 200 production companies engaged in the production and sales of laser products. China has formed four laser industry clusters in Central China, Bohai Bay, Yangtze River Delta and Pearl River Delta. A complete laser industry chain has been formed, covering laser crystals, core components, accessories, lasers, laser systems, laser applications and public service platforms. Representative laser devices on the market include laser cutting machines and carbon dioxide lasers. Marking machine (CO2 laser marking machine), inkjet printer, semiconductor laser marking machine, fiber laser marking machine, this will undoubtedly provide more development space for the Chinese laser industry.
With the development of Chinese companies and the mass production of laser cutting equipment, as well as the continuous establishment of foreign companies in China, the difference in quality and price between domestic and imported products is shrinking. In 2010, the market share of domestically produced equipment has reached 80%. It can be expected that China's laser science and technology will have more brilliant development in the 21st century. In ICF laser drivers, high-power chemical lasers, semiconductor-pumped solid-state lasers, ultra-short ultra-strong lasers, laser ranging and distance measurement, artificial crystals and laser industry, China's laser technology workers will be determined to innovate and climb new peaks. .

Spade bits are used for rough boring in wood. They tend to cause splintering when they emerge from the workpiece. Woodworkers avoid splintering by finishing the hole from the opposite side of the work. Spade bits are flat, with a centering point and two cutters. The cutters are often equipped with spurs in an attempt to ensure a cleaner hole. With their small shank diameters relative to their boring diameters, spade bit shanks often have flats forged or ground into them to prevent slipping in drill chucks.
Some bits are equipped with long shanks and have a small hole drilled through the flat part, allowing them to be used much like a bell-hanger bit. Intended for high speed use, they are used with electric hand drills. Spade bits are also sometimes referred to as "paddle bits".
Spade drill bits are ordinarily available in diameters from 6 to 36 mm, or ¼ to 1½ inches.
