For us to live in the use of the laser has been very common, we have always been able to find a wide range of laser products, laser transmitter. But we know that the laser is a radiation, and today we have laser protective glasses for everyone to talk about the most prominent features of the laser.

Laser has four main characteristics: high brightness, high directivity, high monochromatic and high coherence.

Laser high brightness: the brightness of the solid laser can be as high as 1011W/cm2Sr. Not only that, with high brightness of the laser beam after focusing by the lens, can generate thousands of degrees in the vicinity of the focus is the highest degree of high temperature, which makes it possible to process almost all of the material.

The high directivity of the laser: the high direction of the laser to make it can effectively deliver a long distance, but also to ensure that the focus of the high power density, these two points are important conditions for laser processing.

Laser high monochromatic light: because of the high density of laser, so that the beam can be focused to the focus accurately, and get a high power density.

High coherence of laser: coherence describes the phase relation of each part of the light wave. It is the laser with the singular characteristics described above and it has been widely used in industrial processing.

The benefits of laser is varied, but we should also know that there is actually a laser radiation can hurt us, even the radiation is not reversible, so we need to use the laser protective window of a laser protective equipment to prevent themselves from being hurt.
