Do you know the dangerous distance of the laser pointer?
There is no linear relationship between the laser pointer display and the danger distance. Conversely, the interval between dangers increases with the square root of power. The above example shows that the response rate has increased by 100 times (5 to 500 kilowatts), and the risk divergence distance has increased by 100 square roots or 10 times. This is an important principle. This is also good news for pilots. With the development of consumer lasers, the danger will not increase sharply. If we compare the above two events, we can see how the color affects the visual interference distance of 255 meters compared to a green laser that is 400 meters high... It can be blinded. Similarly, the following two compositions show that the green laser is better than the blue laser. Much more powerful, but the strength and distance are the same. By comparing the 5km/g green laser pointer and the 50km/g green laser pointer, we can understand the impact of this performance on traffic lines. The laser power of 500 megawatts is 100 times that of normal lasers, but it is only ten times longer than normal lasers. Although these numbers are not shown in the figure, nohd will have the same effect. The ncd of a 500-kilowatt laser is 10 times that of a 5-kilowatt laser pointer but it is 100 times that of a 5-kilowatt laser.

When the ability of the Laser pointer increases, the dangerous distance will increase and the dangerous distance can only increase ten times. Usually (the square root of 100 is 10), the higher the radioactivity, the greater the degree of differentiation. When the radiation accelerates, the energy density (radiation amount) will decrease. When the intensity of the rays that are not easily dispersed is not increased, this helps to make the rays safer and reduce nohd. Both of these effects are good news for pilots and others, who worry that the impact will increase the power of the laser. As consumers receive more and more lasers, the increase in hazardous distance (nohd, visual interference) is much smaller than expected. 100 times the laser does not mean that it is 100 times more dangerous. If you assume that the two are the same, your risk "just" increases by 10 times. Of course, since the spread of the signal is generally accompanied by an increase, the loss of light is relatively small.
