Hey guys, I'm new to lasers, especially IR lasers. What is the difference in the different wavelengths? 808 seems to be the most popular on lazerer. Also, as far as burning or heat goes, there are plenty of videos on youtube about what they will burn close up...but out to what distances would you notice the heat from the laser? Specifically from a 2W laser. Like when I think about IR lasers I think about that scene from National Treasure where they set off the heat sensor on the Declaration of Independence from about 10 or so feet away. If I were to hold it on a thermometer at that distance, would I notice a temp change?
