The so-called laser (LASER) is composed of the first letter of each word of the English sentence "Amplification of light by stimulated radiation". By this phrase
It is known that laser is a kind of light.
Light Amplifications by Stimulated Emissions of Radiation
Lasers have the following characteristics compared to natural light.
(1) It is emitted over a long distance without spreading or weakening. (Strong directionality)
(2) It can be concentrated into very fine light through a lens. (Good light concentration)
(3) Consistent wavelength. (High phaseability)
Lasers are called by many names, such as radium, lyser, and so on.
The same laser (laser) is currently used in a wide range of applications, such as laser cutting, laser drilling, laser marking, laser spot removal, etc.
Repeat positioning accuracy of plus or minus 0.01MM below. Domestic equipment YAG small power is generally in the hundreds of thousands to a million ranging from small power fiber is probably also in the 1 million up and down, C02 and high-power fiber is about 180-240 or so. Imported equipment is about 3 million up and down. The recent second half of the boom is really not too good, but the laser is still in a state of development in the country, the demand is still very large, but before investing in the purchase must be positioned, even if the environment is again good to blindly invest in the risk. YAG cutting capacity is generally 5mm or less, fiber optic thin plate has the advantage of speed, the ability to cut thick plates or CO2 is not as good as CO2. CO2 laser general carbon steel 25 or less, stainless steel 12 or less, aluminum alloy 10 or less. Now the mainstream are still CO2, very mature machine type.
