The application of laser pointer in physics
Evolution ensures that our eyes are fully adapted to sunlight. This contains more green areas, so our visual organs are more sensitive to green, which is why the green grass standing on the viewing platform is easier to attract the eye than the brown-blue water in the same environment. The light of the green high powered laser pointer is easier to recognize than the blue one. Therefore, the blue laser pointer must be much brighter than similar laser pointers, which is why in the case of poor quality, the upper performance limit may become a problem. On the other hand, a good model can guarantee a clear presentation even in direct sunlight. On the other hand, depending on the situation, blue is much less than the bright green or red of most laser pointers.

In order for a green laser pointer to emit blue light, it must understand the laws of physics. A photon, a particle of light, can extract a second identical photon from the semiconductor metal if it simply flies over the board in a suitable way. In order for the semiconductor to emit photons, it must first be put in the correct state using an external voltage source (in this case, a battery). From this perspective, buying a blue laser pointer is enough. Just press a button to start. A single photon becomes multiple, but several become multiple only because the photons repeatedly hit the mirrors on both sides and must return through the metal. In this way, the production of photons will continue to oscillate until there is enough light to reach the desired spot on the screen in the form of a laser beam at a certain point. From this perspective, a laser is nothing but a large number of the same photons with the same target.
