Monochrome laser pointer
However, the amplified frequency range is too limited for most electronic applications. Physicists wanted to go further and soon began to study other areas of the electromagnetic spectrum, particularly wavelengths of infrared and visible light. He started the big game.

1. The power output of the laser pointer
It seems obvious now that the higher the mW (milliwatt) power of any laser, the greater the range and brightness it can provide. However, not all users need something that can light a match or pinball, so before jumping straight to the most powerful high power laser pointer beam, you may find it a good idea to think about the application you're going for. Actually use the laser in order.
2. The brightness of the laser pointer
Color There is quite a bit of confusion about laser color when looking at different output powers. The norm is that green light with a frequency of 532nm is always 7 to 10 times brighter than any other color laser of the same power. That means one will be at least 7 times brighter than any other color's 200mW. ,
3. Laser pointer warranty
Because there are so many different options for anyone looking to buy a green laser pointer, you'll want to make sure to do your research and see what types of warranties are available on the model you're considering. Any laser company that doesn't have a warranty or offers less than a 6 month warranty says they don't trust the quality of their product. Always look for the stated warranty period, preferably 6 months or more.
