I was looking to build an array of infa red diodes, and came across this:

Laser Light Solutions Releases Turn-Key, 5-watt Blue Laser Diode System

it seems like magically amazing power for a small price, but it says its only bare chips. Does this make it far more difficult or impossible for a DIY laser? It was easy to use a diode because you just solder wires to the pins and put it in a module, but do bare chips require special treatment? Just looking for some guidence as to weather or not I should buy this

You don't want bare chips unless you are a magician cuz you'll need to be to solder them to a header.

I have a bunch of 635nm 500mW dies, or something close at least. I planned on making a setup that simply clamped the die making the connections so no solder would be needed. After I got the dies and saw how small they are I never even tried. A grain of rice is monolithic compared to a laser die, even a relatively large multimode die.

It's possible to do as Robin has shown but it's not easy at all!

Hehe, I'm betting those are from Chris?

I probably have.... 750 bare dies. I even have some obnoxiously large multimode IRs, that must be meant for like 20W, because they're larger than the emitters on the "7W" C-Mount diodes I have by many times.

In theory, if you could find some sort of solder paste that was incredibly low melting point, I think you could possibly utilize emitters by basically taking a reflow approach. But it's really not going to be easy.

That is the exact process Robin takes, a very closely monitored tec hotplate and indium solder that melts at something like 98c. I can't see it happening, too many places to mess up!
