Now, today lasers can go from less than 5mW all the way up to 5,000mW or 5W. So that means knowing where the burning threshold is and that threshold is at a minimum of 100mW as a general rule. That means that any laser below 100mW will be hard-pressed to burn anything and will flat out not be able to.
How powerful does a laser have to be to burn skin?
Lasers that emit more than 5mW visible light power can cause irreversible eye injury, and higher-powered laser pointers can irritate or burn the skin. While high-powered laser pointers are illegal, they are available on the Internet and in stores, according to the alert.

What does mW mean on a laser pointer?
Burning Laser Pointers. A laser’s power is measured in Milli-Watts (mW) and typically are ranged from 5mW all the way to 1,000mW or 1 Watt. The higher the output of a laser power the brighter it will be, the greater distance it will be visible for, and the greater the burning ability (when over 200mW). 2.

Can a Class 3B laser burn?
Class 3B visible-light lasers are hazardous for eye exposure. They can cause burns to the retina. It is unlikely that a handheld beam aimed from more than a few dozen feet away would cause injury — laser light could not stay on one spot on the retina long enough for heat to build up to injurious levels.

Laser pointers with much higher power output aren’t hard to buy online, however, despite being classed by the FDA as causing immediate skin and eye damage when viewed directly. Blue and violet lasers can be particularly dangerous because human eyes are least sensitive to these color frequencies.
What will a 15w laser cut?
It is possible to engrave on most organic materials, such as wood, plastic, leather, and also painted metal. The cutting capabilities are a lot more limited, including mostly paper, thin fabric, and veneer wood. However, the primary use case for this kind of laser is probably engraving on wood.
What can a 6w laser cut?
~6 W will cut 2-3 mm wood with one pass or 4-5 mm with multiple passes. ~8 W can cut 4-5 mm wood with a single pass or thicker wood with multiple passes. ~10 W can cut 5 mm with one pass or up to 10 mm with a double beam laser attachment and several passes.
