Re: Multiple cube beam combiner "it can be done"..... Has anyone seen this article? Are we talking 4 digit number cost here?

So do I understand correctly that there's no harm in using resistors with higher resistance as balancing resistors, just to be on the safe side? And what is the idea of running them as 2 pairs, instead of having a balancing resistor for each individual diode? Thank you all so much.

How can I calc what resistor I need, given the max operating current and voltage of the diodes? I don't have problem with a series setup its just I dont think the drivers I have in mind can supply so much voltage. One is a modified Simpledrive up to 4.5 Amp output and the other is a Flexmod.

I have found cheap source of 4.5 Amp high current Arduino and DAC controllable laser drivers. If I have many diodes I want to power at once (0.8 Amps each, 4 of them , http://www.mitsubishielectric.com/semiconductors/content/product/opt/laserdevice/ldindis/638nm/ml501p73_p1245.pdf ) can I and...

Seems like diodes are very sensitive to heat and can die if not properly cooled, so I'm still wondering why we don't have female plugs on which to solder or crimp cables instead which can be connected/disconnected from the laser diode instead. Aixiz sells one but for testing. Anyway, since...
