Im Paulo from Brasil, and i wanna buy red or green laser pointers with maximum potency, like this:
www*youtube*com/watch?v=Xz4v8g6Y4mI <- Remove the * and put .
www*youtube*com/watch?v=Sf3M-_RUSCM <- Remove the * and put .
But here in Brasil its very hard to find it, and i wanna know who can do the laser pen (about 3 of this) and send-me, i pay for it and for shipping.
welcome to LPF! the second video is really a load of crap - yes, you can make a 5mW green laser higher power, but it will generally die within days, if not hours or minutes. you've got a few good choices when it comes to high powered pens, depending on what you want... on dealextreme you can find some really cheap lasers that will burn, but they're really not that well made and often emit quite a bit of infrared, which can be really bad. otherwise, you can go to novalasers, and get say an X-85 or X-105. both places will probably ship to brazil, i'm not sure how much it would cost though. or maybe someone here can give you a better deal on a second hand green or a homemade red - the greens will be much brighter though!
create fire? really the only fire you'll make with a portable laser is on things like matches, where enough heat makes the match burst into flame by itself - when i'm burning things like black paper/plastic, it doesn't really make any fire, it just burns a hole/line through it.
