Nice job-very clean work -- well thought out unit. Great photos.7 of one color - just to be clear.
one of my projectors has 6 (3 pairs of single modes in pbs cubes) then combined with dichroics before they hit the scanner, I could have added a 405 for 7.
Of course its still under a watt - BUT a perfect beam.
I understand your point and what you made. The OP was talking about 7 individual 7W watt lasers as in 7 W hand helds--has to be NUBM44=V2 450nm 7W multimode blue laser diodes he was talking about I concluded.
THE OP doesn't seem to know both Star Wars "death stars" combine 8 beams.
8 a circle in one version and 8 beams, 7 beams in a circle + 1 dead center, in version II of the "Death Star"
I mean really, years of work on a 5 foot wide detailed model, thousands of dollars and he gets the number of beams in a "Death Star " wrong--doesn't get the number of beams correct---go figure?
Still smells a bit funny. Maybe he will post a photo of the model he made?
An explanation/graphic representation the 2 configurations of the "Death Star's" 8 beams, not 7.
