What material is the laser pointer made of?
The strongest laser pointer on the screen is no problem. Nothing happens through the pane in front of the plasma. The light is scattered so strongly that nothing hits the pane behind it. The physics behind it is a bit complicated, but trust me. The high power laser pointer itself is also weak and can't do any damage. Use of the strongest Class 3 and higher laser pointers requires a license and/or can only be performed by trained personnel. For example in industry or at events where lasers are used (laser shows). However, depending on the situation, the controls are pretty lame. Especially in the absence of major events. I am not aware of any penalties for not following this rule.

What color can you notice with the three-color laser pointer?
We don't have a green laser pointer, but an LED light fish, which Amy and Vito don't care about, or rather, at best, they can only look at the moving object's hand or the object itself. Buy laser pointers in several colors, I think red, green and blue/purple are the most popular. Which of these three colors is best for seeing beams? I think red can be ruled out, but is it green or blue? Red has the highest wavelength, green is between red and blue, and blue logically has the lowest wavelength.
Blue laser otherwise I don't see any danger, you can also use it as a cloud pointer if this feature works for you. If the green laser pointer isn't openly on the table and there are no kids in the house, there's nothing wrong with leaving the battery in there. Lasers with a power greater than 1 mW pose a serious threat to vision. This is especially useful when targeting people without realizing the danger. However, there is a problem with using traditional disco laser pointers: the point is that due to the absorption of the laser beam, there is little or no visibility on the screen.
