that would be quite excellently suitable for a beam table.

suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

you can buy them now for around 350$ iirc
the current cost in parts for a dual diode red doing 1.2W not labor. parts
is about 300$ ish depending on what you source.
So not too bad for the insane power

2 of these, some corrective optics & a PBS cube and I'm set!!

yup... 1k$ for 10W of red is pretty amazing.

Now if I can just find some reasonably priced green.....

that's pushing into laserscope territory...

yea green is my limit too atm.
Just finished a 1.2W 635nm build.
And got to say even 1.2W is amazingly bright.
I dont even know what i would do with 4W.
Ohh hell i would just get a 12W projector,
4W of 445 out of 2 9mm diodes then 1 of these reds and a kidney for the green.
That sounds about right.

This would be nice in a lumia projector. Some bright red scatter to compete with the apparent brightness of 532 and the cheap wattage of 445.
If you're the smartest person in the room, then you're in the wrong room.

There are a couple of issues that need to be answered about these diodes.
If these were a one time production that cannot be sourced again or even identified then what is the current world's supply of these diodes in an actual number and are they all from Lazeerer and priced @ $375 each?
The divergence is, in other words the real spread of this diode, is not well described by this test because the size of the beam is so large. When you take two distances from the diode that are both finite and in this case fairly close to each other then the divergence can be made to vary a lot depending on the size of the beam leaving the first lens. I will bet that if DTR had a slightly longer FL lens that allowed him to position it a few cm farther from the diode and the beam started at 10 mm that it would have a divergence that calculates as ZERO. Similarly, if the beam was focused by stronger lens @ 4mm then the spot @ 25' would be 20mm then the divergence would calculate @ 2.13mrad.
