When I found out that some of the problems were true, I was afraid that some of these people might get a driver’s license and forget what the big vendors did when you jumped on at 70 mph. I will leave your world soon, a gift and choice for the few men who can discover their unique genetic causes of bipolar genes. They love God and his son instead of parents, girlfriends, wives, and yours. Kid, the laser pointer is ultimately your own life.
The glare reflected from the cockpit obviously disturbs any pilot, so anyone can act recklessly, but it is also reckless to shine an improperly adjusted full beam into the cockpit of a bus while driving. Compared with car headlights, handheld lasers have the least energy. I hope to oppose the legislation to point lasers at airplanes out of fear that they might be used as target painting equipment, rather than ignorance of the physics involved.
Most laser pointers produce milliwatts of power, which if collimated well, is good for traveling several miles. Collimation is a measure of how much a beam is magnified over a given distance. Cheap laser pointers usually do not collimate well, although this situation is changing rapidly. So it's really not a question of how far they can go.
Depends on the power... Regulatory laser pointer with Class II green laser pointer (visible light below 5mW) can be seen in ordinary air, assuming the normal divergence of the laser diode can be seen within a few hundred meters... I bought an unregulated laser with a Class IIIb laser (60mW green) in the Chinese market for about US$10, which can pass through 2 kilometers of fog.
If you mean in the atmosphere of the earth, it depends to some extent on the wavelength of the laser, and it is also due to the absorption of atmospheric gases. A CO2 laser with a power of 100mW will not go very far, because it will encounter enough CO2 and be absorbed quickly-I guess it's about a few miles. If you mean 100MW, then it will leave the atmosphere.
