What is a rotating laser pointer?
The popularity of the red laser pointer is now replaced by the green high powered laser pointer, which can be seen from a greater distance. The human eye responds to green light about 50 times better than the human eye. The red laser pointer, which is why it looks so bright, except that the old red laser pointer is only a mile away. A new green battery, powered by only one AAA battery, does not exceed the mark and can send a beam of more than two miles. Lasers have reached incredible diversity in the first half of this century. The purchased laser pointer is usually used as a cat toy in supermarkets, gifts or barcode readers. The annual production of hundreds of millions of laser diodes is an important part of everyday consumer products such as CD and DVD players.

The energy and light from the laser pointer are concentrated in a very small light cone to achieve a relatively high intensity. Therefore, its marking power is much lower than that of ordinary bulbs, and the intensity of one-time luminescence is very large. The power marked on the laser pointer is the output power. The typical input power of a 50mW pointer is about 0.5W, and the difference is even greater. As long as 500mw, any wavelength can burn well. If the energy density is short, the point where the wavelength is short and the energy density is long is high, so if the combustion power is one point, if the wavelength is short, I think it will be beneficial. In addition, many green laser pointer use solid-state laser pointers. Although they are lasers, they are focused due to their characteristics. Even if there is a difference between the lenses that collect light, the power of the energy will change. I think it will be different.
