Lately all my friends have been asking me which diode is the best choice for building a laser for burning? Several of them are considering constructing their own handhelds, including myself, and wanna know if their are any other diodes that compete with the nubm44 in terms of power? Has anyone tested diodes head to head to see which burns best? A couple of my buddies have an unlimited budget and are looking to build the most powerful pointer possible in terms of setting things on fire.
