    We were just doing some lectures briefly involving something called a bar diode recently. I didn't get many details on them, but we did get to see a few up close. They looked sort of like little glass tubes and appearantly they're used in a few high-intensity light applications (laser diodes maybe?) but it's real hard finding data on them.

    I googled up a few sites, but it was mostly brochures and industry talk. Does anybody know a good site for info on these bar diodes?

    Laser diode bars are arrays of laser diode chips mounted to a big heatsink, often attached to forced cooling. Sometimes the assemblies have optics and focus the output into fiber optic lines.

    The glass tubes part doesn't make sense - what was the topic of the lecture?

    Was digging around the web, I've never heard of the "AL081C60W" types before - is this similar to what you saw?

    I have a couple shots of a defunt assembly. The are two of these devices in each picture with 9 rods on one assembly and 12 on the other. I'm uncertain if the rods are for producing or maybe focusing the light. The details at the time were really vague.

    Well, this is what 2D laser stack looks like...

    Do you have a magnifying glass? I have no idea of what that is...
