Besides, when you are not at home, who will play with your pet? This is where the cat laser pointer comes in: you can easily move it on the sofa, or find a high-tech solution that allows your camera to use your smartphone to play laser games with your pet even at a distance.
It may be helpful to give you an idea of optical power levels. One hundred microwatts of light power is approximately equivalent to a bright room. I measured about 600 microwatts of solar power on a clear afternoon using a sensor with a diameter of about 1 inch and broadband measurement capabilities (both visible and invisible wavelengths). 1 milliwatt (1000 microwatts) is the standard laser pointer power.
If he doesn't have a double-sided laser pointer (not a small toy, super strong), where does the laser come from? At different times you can see the laser hitting the crowd and the wall behind him, and once he held the beam almost completely vertically.
I don't know of any gyroscope laser machine that can make it look like he is holding a green laser pointer, but he doesn't actually hold them. (In addition, if the laser beam touches the inside of his hand at any point, it will destroy the effect, and it is almost impossible to be so precise that he will not accidentally touch the laser at any time.)
Ordinary low-power laser pointers are considered "safe" in a specific sense. The "safety" of these lasers means "you can blink and close your eyes before permanent damage to the retina". If the laser is actually 1 km away from the aircraft, the beam will spread significantly and is likely to be weak enough to achieve a stronger definition of "safe", that is, it will not cause eye damage even if it starts to enter the beam.
