mine arrived today! Thanks!
Now I need to order some lasers and hassle dave for optics..

If I were to get one which diodes would you recommend to try to mix?
It depends mainly on what do you want : best beam quality or as much power as you can ?
What I did for example to keep a low divergence with a small beam diameter, is to couple one quad diode module of 5.5W 462nm with another quad diode module of 6W 445nm...
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.
Do the quad diodes have a

vertical arrangement of the beams before correction or
..
horizontal arrangement?
If its the former, I think the beams would be too fat, if its the latter, how is that corrected? I think with cylindricals you need the beams in the middle, not the edges of the lens.
I don't think it will be right to ask the manufacturer, I know you can open them up and check if you have them but it might still be a design secret he wouldn't want to just teach everyone.
Are they polarized btw?
@ " Horizontal arrangement. I believe it's cylindrical lenses"
....sounds unlikely (but possible) usually, a horizontal knife edge arrangement will use prisms and almost always, when PBS is being used (highly likely in this case), unless Phil has decided to sell polarised add on modules without mentioning it to his clients...(a big selling point would be missed here).
Reasoning:
If you knife edge horizontally, the beam is flat and wide which means unless you add an unnecessary reflection/mirror (not usually recommended unless strictly obligatory for space reasons) to the path of the reflected input into the PBS, the distance from collimator to cyl lens will be different for each side of said beam (cos its WIDE) and gets wider with every beam you add. This effectively eliminates any chance of getting a perfect focus in the farfield, and/or, will increase losses if you use a tight spatial filter.
(always assuming here that you don't mix upwards into the PBS)
I think anyway that Phil would prefer you to ask him directly (that way he can say no if he wants to), rather than getting one of his clients (who is probably a friend) to open the lid on a new (virgin/squeaky clean/spotless) set of optics. What's more, I think he relies more on his skill and knowledge, rather than "secrets" to keep himself in business. I am fairly sure, that if you asked him, he would tell you.
Knowing how someone apparently did something, will not ensure that you can achieve the same results by copying them.
There is invariably a bit more to it than meets the eye....try painting a Rembrandt,Goya or a VanGogh or even get a machine to do it...it just aint the same!
However I have to admit, recognising where any possible errors are hiding, is always helpful when trying to design/build something.
Cheers
