What is the connection between laser pointer power and wavelength
First, the greater the laser divergence Angle, the closer the target distance. The low beam divergence laser shows better directivity than the large divergence laser. In the same emission area, the longer the laser designator, the greater the laser divergence Angle. Therefore, red laser has longer beam visibility than infrared laser. However, different types of laser Pointers have different mechanisms. It is difficult to achieve the same luminous area of output power. For example, an 808 nm infrared laser has a larger emission region than a 980 nm infrared laser. Under the same output power, 808nm infrared laser has larger beam divergence Angle than 980nm infrared laser pointer. This is a portable and durable blue laser pointer. This is a good indicator for replacing Pointers. It can be used for education. Compact, lightweight and easy to use. Therefore, you can carry it with you anytime and anywhere.

The strongest high powered laser Pointers can be used for hiking and outdoor activities. High-power laser Pointers are smart enough to drive away large wildlife and help you hike or camp. In this case, the laser pointer can also serve as a handy survival tool, as it can act as an emergency signal, allowing aircraft and other stakeholders to see rescue signals at great distances during the day and night. For example, on the night of August 2010, rescue teams found a red laser pointer and rescued two men and a boy from a swamp. Such lasers can cause damage if the beam goes directly into the eye. This is usually the case with lasers with power outputs of 5 to 500 mW. The high power end lasers in this class pose a fire risk and may cause minor skin burns. It's the same thing as burning a laser pointer.
