Hello,
I am Noctua and i have 14 years old :D
So, today i had the idea of building a sort of non powerful laser gun.I plan to focus the light with converging lens.I will use a powerful laser Pointer.So, here is my questions:

If I absurdly concentrate a laser , the concentrated light would be "more hot" than the light that has not been concentrated ?

Which laser pointer should I use? More watts, more powerful?

I think i have only that questions...Please, answer me :DD Thanks!

Sorry for bad english, i am from Brazil.

Be careful kid, laser is no plaything. What you said there are all true. Focused pointing laser may not be damaging to skin but it can be harmful for delicate tissue such as people's eyes. What is the purpose of your project, is it for playing tool or for physical experiment? Either way never point it (even the unfocused beam) to anyone's eye.

I'm sorry but we can't help you. Lasers are NOT toys and you should only be working with them if you have a specific purpose in mind. Otherwise you are very likely to injure yourself or someone around you, possibly quite seriously. Find another project to do before you blind someone or burn a house down.
