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

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


4mw) to burn paper?

Sure; think clamps.

Enough to make it reach 451F. ;>)

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?
