The difference between blue and green laser pointers

The Green laser pointer has a precise flight direction, so if there is nothing in the air, the light will not hit any place other than the front, so it will not be seen. You can see it because it hits the dust, dust, smoke, mist, etc. in the air and diffusely reflects it. In an environment where an air purifier is used in the room, it will not look too beautiful. You can easily make it easier to see by pouring hot water into a container to vaporize it, or collecting cigarette smoke to diffuse it. The tiny size of the blue laser pointer allows photons to be confined to a few states, while the bass gallery effect forces the photons until the accumulated light waves accumulate enough energy to pass through the structure. The result is that the laser pointer achieves extremely high working efficiency with a low energy threshold.
