As others have said, the quoted power output of laser pointer manufactured overseas is usually very far. Most importantly, green lasers are usually made by irradiating infrared light on a crystal to produce green. In these settings, there is usually a beam or remaining infrared light next to the green, which is very dangerous. I recommend using the 1-5 milliwatt laser pointer from a more well-known source before starting to use the "100+ milliwatt" option elsewhere.
Can people on the ground use laser pointers to harm aircraft? How does this work? By the way, the beautiful cockpit image of the green laser is not 1 mW, because your standard diode is rated at 100 mW in the critical chain, just like the ones that flicker occasionally on the market register. This transverse electromagnetic mode is an important factor in how much energy reaches a given distance without losing energy.
The flashing pilot can't just press the "pause" button on the plane and wait 15 minutes for his vision to be clear before continuing the flight. He needed his eyes until the plane landed on the ground. Pilots using laser flash may not be able to continue flying the plane (or helicopter), and the result may be a crash. If the plane crashes, the fact that the pilot’s eyes will not be permanently damaged is not very comfortable.
If you think the laser pointer is harmless, please try the following: Use an ordinary green laser pointer with a power of 5 mW or lower. Drive to a place where there are no street lights in the country, so it's really dark. Wait until there is a new moon, or there is only a small new moon, so the light is mainly starlight. Let your eyes adjust to the darkness for an hour.
You will find that you can still see under the starlight and a little moonlight. Now try to walk along the road or path in the dark. When you do this, your friend is standing about 100 feet away. Ask them to shine the laser pointer directly on your face for a few seconds without prior warning. See if you can continue walking during and after the flash. Now imagine that you are flying a several-ton plane several hundred feet above the ground,
