The NUBM44 is the highest power diode right now, but it's divergence is so bad that there are better options for a burning laser. A 3 watt 445nm 9mm diode would work even better unless you are willing to put the extra optics to correct it's terrible beam divergence. I'll look for the links you want if you still want to use this diode.
Sure that would be great, so could you send the link to the 3 watt that you would get for the s4x host, and is there another site that you would recommend for bigger hosts?
Also to use the 6 watt and focus it would I need to get what extra, just incase I wanted to go that way aswell, but if you could link the 3 watt aswell that would be great. Thanks
