How many watts is a visible laser?
The power for an average laser pointer is a measly 0.005 watts. However, because of the narrow path of the laser beam, if you pointed it directly at your eye from an arm’s length away, the little illuminated dot on your eyeball would be 30 times brighter than the midday sun. So, don’t do this at home, or anywhere.
How strong does a laser pointer have to be to start a fire?
As a rule, a laser that can light a match, pop a balloon, or cut electrical tape, will need to be over 200mW or 300mW, and the higher the power the better. For example, a 3,000mW blue laser pointer will be a fast-acting burning laser tool whereas a 200mW unit will just be able to pop a black balloon.
How bright does a laser have to be to blind you?

Can a laser pointer reach the moon?
The typical red laser pointer is about 5 milliwatts, and a good one has a tight enough beam to actually hit the Moon—though it’d be spread out over a large fraction of the surface when it got there. The atmosphere would distort the beam a bit, and absorb some of it, but most of the light would make it.
Can a laser pointer damage a phone camera?
It is virtually impossible to protect your smartphone camera lens from lasers, so if they take a direct hit, it will damage your cameras lens permanently. The only fix is a new lens which in reality will mean a new phone.
