High-power laser pointer can repel large animals
Light produces a specific laser diode. The front lens focuses the light on the beam. How to strengthen Considering this point, how to overcome the maximum distance depends on the emission output of the laser diode. Performance is measured in milliwatts. In order to more easily divide the segmented laser pointer into different categories. The scale ranges from level 1 to level 4, the lowest measurement level for level 1 lasers, and the highest level for the 4 version. In this category, you can also see if the laser pointer beam entering your eyes is dangerous or harmless. Prolonged lighting or using a magnifying glass can cause health problems. Class IV and IIIA lasers are dangerous lasers that can damage the retina. Don't rely on people.

If the question of how far the light of the high powered laser can travel is correct, as long as the light is not absorbed or scattered in the atmosphere, there is no limit to the correct answer. However, the spread of the beam will eventually increase the area of the beam. Even if the total power remains the same, it will decrease on the screen. Therefore, the airplane pilot will not be disturbed by the remaining small intensity when looking down on this beam from an altitude of 10 kilometers. The laser pointer can be used on foot or outdoors. High-power laser pointers are suitable for hiking and camping because they will be slightly frightened by large wild animals.
