lasers have just as hard a time igniting wet material as matches do, though I suppose a laser could be on for longer than a match lasts. are you sure a lighter isn't a more practical solution? you'd need safety glasses as well as the laser to start a fire. lasers capable of igniting say, a stick, need to be stronger than ones that could just blacken it and cause it to slowly smolder. if you dont use nesting material, and need to ignite a stick directly, I'd estimate at least 2W, or pretty close would be needed, which pretty much limits you to a 445nm laser. less power could make an ember in some nesting, which you could carefully blow on to get flame. like I said though, lasers don't ignite wet stuff any more easily.
I doubt this is your best solution, there are wind resistant lighters, like the butane torch ones.
