I haven't heard much about them, but the wavelength is very close to a nice water absorption peak. I've only ever seen 1470 nm diodes at low power, except medical take-outs (I guess they are used for vericose vein removal). I was wondering if anyone here has experience with them. Obviously, being well into the NIR spectrum, I wouldn't recommend any experiments without proper IR laser safety.
I'm not sure what kind of power and optics you'd need to boil water, but I bet it'd take a lot more power than the 100 mW diodes I've seen for sale.
