cd, yes. i'm using two sets prism pairs. one diode is rotated H and one diode is rotated V so you have to rotate the prism pairs as well.
i'm using this system in my rgb rig. these diodes are so crazy powerful that i don't care about losses. the intent was to get the best beam that i possibly could without resorting to fiber.

I cannot understand the beam shaping optics on the LD on the right....almost looks like cylinderical optics ??? or maybe Anamorphic Prisms turned 90 degree ???
Anyway.....I MUST use knife edging to do a quad !!! My test set up uses Daves LD mounts and Flexmounts. My name for it ( MUST name everything ) is the Zod Dual...mmm or Zuul.....Of Course !!!
I also do not understand why you would choose more optics loss by going thru two sets of beam shaping optics.....then go to combining ??? Perhaps SD can further explain his set up ?????But....his beam SURE looks great !!! That is for sure !!!
Like I said....this is just a set up to experiment....B4 I drill and tap many, many mounting holes in Copper !!!
Oh...And...Go with the JML PBS....I bet it is the best efficiency we are going to see !!!!! 97% efficiency on transmission and 95 % efficiency on reflectance !!!
And for the asphericals...go with the O Like and Simons Prisms for beam shaping...ALL My opinion....subject to change daily !!! haha

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.
