I want to build a 2 watt 808nm laser with an adjustable focus using an Aixiz module drilled larger to accept a larger 2 watt I.R. diode (9mm). I have seen on here that I.R. pointers have bad divergance...if I use a glass focusing lens would it pop a balloon at the same distance as a 650 nm red laser that's 200mw but be stronger because it has more power? I realize the emmitter size has alot to do with it.
