Burning paper requires 1 watt (1000 mW), which is more than what most laser pointers can achieve without modifications For comparison: Popping balloons or lighting matches râ¦equires roughly 100 mW (which is the high end mW range of most commonly found laser pointers) Note: laser pointers anywhere near 100 mW and up are very dangerous to the eyes and ...
A Class 3R laser is a continuous wave laser, which may produce up to five times the emission limit for Class 1, or Class 2 lasers. Although the MPE can be exceeded, the risk of injury is low. The laser can produce no more than 5 mW in the visible region. Visible class 3R is similar to class IIIA in the US regulations.
