Laser pointer multi-function
Most lasers have the same functions, such as pointing, remote pointing and classroom use by teachers. There are toys, many people use them to entertain and play with pets, you need to use other functions depending on the power. For example, a crow laser pointer needs to use a certain amount of power and wavelength to effectively repel birds. Without the use of a specific wavelength of power, the high powered laser will not be visible to the bird's field of vision. There is also a power factor that only high-power lasers can shine farther. The higher the output, the easier it is to light a match.

For use in classrooms and meetings, you can choose a low power red laser pointer. If you want to get rid of birds, you can choose a specific laser pointer. If you want to experience super powerful lasers at long distances, you can choose the strongest laser pointer. Green laser Pointers are used because of their high visibility. This is because products commonly used as laser Pointers also have legal output limits, so a more "easy to see" color makes more sense even if the output is the same. There is also a view that green lasers are easier to detect than red for use in surgery and visual recognition in patients with congenital color blindness.
