Eight Diode Knife Edge Array - best practice?
I've seen 2X 4 diode knife edge arrays which are both sent (with a rotator on one side) into a PBS cube to combine eight, but I want to combine eight which are all the same polarity using a simple knife edge array. Can someone point me towards a photo of an eight diode array so I can get an idea of how wide the beam will be for 1 watt green diodes? I don't have room for a PBS cube.
I'm thinking two levels of 4 x in a line to make a:
::::
pattern is the way I want to go. Has anyone done that? Where four are at one level, then another four in front or back at another level, or is it better to alternate each diode to their own level to interleave them that way? Lasertack used to sell 4x arrays which produced a :: pattern doing that, but no longer sell them.
