I just saw Alex2893 has an Jet Lasers Dazzler for sale that uses a fiber coupled multimode diode and produces a round spot, effectively neutralizing the naturally bad divergence of the laser diode. It got the gears turning in my head and now I'm wondering if it's possible to this with the new NUBM0G or JLD-470 diodes for 7W of ~470nm round laser dot goodness.
I was unsuccessful at finding a module that allows you to press in diode and get a fiber out the other side. I assume that the alignment between the laser die and the end of the fiber is something that needs to be done by hand with precise tools and simply pressing a diode into a module that has fiber output is not going to cut it, but thats just my guess at the mechanics. But in my searching I did come across this little contraption:
If I could somehow get three of these new 470nm diodes fiber coupled the resulting output would be a sight to behold! Is this a fools dream or something that could be feasible?
