Hi arduino Forum
I wanted to know if the color of a laser pointer has anything to do with how strong it is ( mW, W, MW, dont know strong lasers can be ). Many people say that red lasers are the weakest and blue or green ones the strongest. But I have already seen green ones with 5mW and red ones with 250mW. And what about purple an Infra red lasers? I think the element to color them is called Yttrium so does maybe have effect on the wavelenght?
