I found a laser which could do that at a swap meet in Melbourne. I think it would have cost me about 120 AUD, cash only because you need a license to own a laser like that. The owner showed me how he could use it to set fire to box made of lightweight pine.
Its a neat toy and I was tempted but I knew it would always be a liability to own something dangerous and moderately illegal. It would only take some nut near me to flash one at a police helicopter and I could be in real trouble.
