It should go on forever unless there's something in its way or the battery isn't full
A 200 mw laser should be able to hit a person from over 100 miles. That is of course if it has full battery
about 2 metres love
under 5 miles
Someone can purchase a 100 mw laser pointer at any online or physical professional laser pointer company, as well as in large amounts of wholesale product online.
300 milliwatts is brighter and stronger
Any light beam will go on forever, though it will become attenuated, if not absorbed by intervening matter.
It is very powerful, falling into the "3B" class. Classes were determined by levels that can cause a lesion. The UltraViolet laser is far more dangerous than the visible laser. In the visible range, a continuous laser classes are: Class 1: up to 0.39 mW. Class 2: 0.39 mW to 1 mW. Class 3A: of 1 to 5 mW. Class 3B: 5 to 500 mW. Class 4: beyond 500 mW.
my guess? about 10,000 mw.....
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 requires 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 can cause permanent degrading of vision (some doctors say any laser above 5 mW can cause eye damage), so use with caution and never point at anyone's face
No
