100mW will burn, but you'll want a focus feature to maximize power density. You'll also need safety goggles.Sorry for not introduced myself but thank you for answered me, i'm not good in English so is hard for me to write. I will update my profile. I will use the laser for burn small objects 100 mw are enough? If I use magnifying lens whit the laser it can burn better?
Laser pointer store is better than most Chinese sellers, but I still doubt that they individually meter their lasers.What about this one https://laserpointerstore.com/laser-pointers/by-colors/green-lasers/301-prome-series-laser-pointer
Someone can confirm me that actually do 80mW
