Laser is another major invention of human beings after nuclear energy, computers and semiconductors since the 20th century. It is called "the fastest knife", "the most accurate ruler" and "the brightest light".Lasers are widely used, laser cutting, laser marking, laser engraving, laser beauty and more.So, what are the characteristics of the laser? The laser has four main characteristics: high brightness, high directivity, high monochromaticity and high coherence.


High brightness of laser:the brightness of solid state laser can be up to 1011W/cm2Sr. The high brightness of the laser: the brightness of the solid laser can be as high as 1011w/ cm2sr. In addition, When the laser beam with high brightness is focused by the lens, it can generate thousands of degrees or even thousands of degrees near the focus, which makes it possible to process almost all materials.


High directivity of the laser: The high directivity of the laser enables it to efficiently transmit longer distances while ensuring extremely high power density for focusing, both of which are important conditions for laser processing.


High monochromaticity of the laser: Due to the extremely high monochromaticity of the laser, the beam is precisely focused to the focus, resulting in a very high power density.


High coherence of laser:Coherence mainly describes the phase relationship of various parts of the light wave.

It is the laser that has the singular characteristics as described above .Therefore, it has been widely used in industrial processing.
