verbal diarrhea?

Nice pics "Doc"

I have a question, when you guys are talking about a "TEC" Do you mean something like this: (See attachement)

Or something similar, perhaps a link to where to get a nice one?

ANother question, Dosnt it get Condense/Moisture?

Thank you.

PS: Sry about the post above but i tried posting 20times and it didnt work, i discovered that there is some bug inserting ebay links.. i tried inserting this link for the TEC:

These diodes certainly lend themselves to knife edging.

doc can you give us some into on lens used and beam spec?

Yep, that's what we're talking about.

No need to worry about condensation, unless you plan to cool below ambient.

And who would like a deep frozen laser diode anyway.... Then again, maybe we could crank out 4W of a single with a TEC at -18C!

As stated above Andy; uncoated 3 element Aixis, inside face of the module sooted to kill internal reflections from the chrome (causes allsorts of random artifacts and side splashes in my experience).

Beam is approx 4.5 x 1.5mm at aperture; I haven't measured the divergence yet but I'd estimate slightly over 2mrad for the fast axis, certainly well usable for beams as-is.

sorry must have missed where you mentioned the optics.

thanks

Ok I'm looking at the relative brightness chart and find
660nm-.061
532nm- .885
445nm- .042

So does this work out as 1 part green to 22 parts blue to 15 parts red?

1mw 532=22mw 445=15mw 660?

23mw green/500mw blue/341 mw red?

just some general dicking around

Ok I have some TEC's, but no driver. Are we just feeding power to the TEC and letting it cool as much as it can, or is there some sort of feedback?

..inside face of the module sooted...

Doc,

Please, can you explain how you achieve this?
