Combining multiple pen lasers 4mW to burn paper is this poss

Greetings, All

Is it possible to combine multiple pen lasers angled down at one point (around 4mw) to burn paper?

What wattage is needed for a laser to burn paper?

TIA

Sure; think clamps.

Enough to make it reach 451F. ;&gt

You will need so many, that it would be impossible to hold them all, in a
tight enough area. It takes a fairly strong laser to burn paper. The power
output per unit distance from the laser output, falls off to the inverse
square law factor.

I would not be able to tell you off hand what power output would be
required, but it would be considered in the range to be a lethal laser.
Also, proper safety practices, protection, and eyewear is essential when
working with high power lasers. These lasers do not give a second chance.

Inverse square law applies to well collimated beam? How so?
