Green Laser Pointers- Different Power Types

Like anything else, green laser pointers come in a variety of options. The biggest variance between different types of green laser pointers is usually the power. First of all, the power is always measured in megawatts (mw). As you shop around, you will see most green laser pointers hovering at 5 mw. This is the most common power wattage, and the highest allowed by the FDA. Lasers over 5 mw need to be registered with the FDA. OEM green laser pointers are often at higher powers, and are legal in most countries. These come in 10, 15, and 20 mw. Some of the most powerful green laser pointers are at 40 mw and up to 120 mw. These lasers are used in the U.S. military and for commercial and industrial use.

You may purhase powerful OEM green laser pointers from many places, and it is not illegal. However, you have use them for personal use (like star gazing or physics labs) and not for street use. On no occasion are you to shine green laser pointers at aircraft. To be safe, purchase 5 mw lasers that are fine tuned as close as possible to this power outage. These laser often have a range of five miles and are clearly visible through the air.
