Can a 5mW laser start a fire?
Now, today lasers can go from less than 5mW all the way up to 5,000mW or 5W. So that means knowing where the burning threshold is and that threshold is at a minimum of 100mW as a general rule. That means that any laser below 100mW will be hard-pressed to burn anything and will flat out not be able to.
What can you do with a green laser?
Green lasers are used by astronomers to point out celestial bodies to other people. This type of laser is more effective for astronomical purposes than other colored lasers because of its power. Green lasers can be used for astronomy by hand or by attaching them to a telescope.

What kind of tape can you use to burn a laser?
Electrical tape is nice because it holds strong enough and looks decent. This creates a much more professional look but in turn requires much more work, the nice thing is it is easily removable and can be used on any of these lasers.
Are there any drawbacks to a Laser Burn?
Its clear that it doesnt actually increase the amount power it just focuses it at a specific point, this is one drawback to this burning method because your laser wont behave like a normal laser point after this because past the focal point your beam will diverge, acting more like a flashlight.
