90° Turning mirror?

[mfo]

I'm not doing this any time soon, but I'm thinking of putting together a white laser, similar to Rog's. Anyhow, please refer to the image.

Those cubes that merge the beams, those are called 90° turning mirrors, right?
If not, what are they called, and more importantly where can I buy them? I know Rog's tutorial says the PS3 sled but I don't see any on eBay. Thanks once again guys n gals!

They are called polarized beam splitter cubes or PBS cubes. You don't need the PS3 sled, you can get better result with the optics in the PHR sled. Search for RGV laser and you'll find allot of info about this.

There are PBS cubes in both the PS3 and PHR sleds. I believe his first 7 color build used the PS3 sled but now he uses the smaller PHR sled, hence the confusion.

PHR sled will give more output power, but making rgv laser with PS3 sled is easier.

I saw the PHR sled....I must admit that's one sexy build. So small...

They can't BOTH be PBS cubes, otherwise it wouldn't work. One or BOTH must be Dichroic mirrors.

I think the first one is a PBS, as you have to rotate the red and violet to achieve maximum transmission/reflection.

So, can we use PBS cubes from a phr sled for this project? I mean those who want to make such a project.

 

[Gryphon]

Absolutely, there is even a kit for build a white laser using the PHR sled
