Smile Reflecting Laser

Complete noob question but;

Can reflecting light from a laser increase its burning power?
Does it do anything?

Default Re: Reflecting Laser

reflecting Laser Light off a flat reflecting mirror
can only decrease the Laser's beam due to the
losses in the optics of the mirror.

ah i see, i was under the assumption it somehow worked the same as to how reflecting sunlight off a convex/cave mirror increased its burning power, dont mind me, just a learning noob!

Default Re: Reflecting Laser

All you are doing with a "convex/cave mirror" is
concentrating the available light onto a smaller
surface increasing the power density (W/cm2).

You are not increasing the original Power.

Like the Sun and a magnifying glass..
As I stated above... it is called Power Density..
Do a Google search on that term...

Default Re: Reflecting Laser

It'd probably be easier for you to use a lens rather than a mirror. Mirrors are usually better for concentrating large surfaces into a small zone, not a laser beam which is probably already quite small.
