Where to find a dichro for combining all colors?

[Midknight]

Where could you get a dichro for combining 2 650nm beams. One for combining 2 405nm beams. And if there is such thing. One for combining one 405nm beam with one 532nm beam. And what would you use to combine RGB to get white?

I have one for rgb > WHITE or Vice versa on ebay right now It's a little large, but it will do. Same user name. Item number: 290243954501

Nice. I would buy it if it was smaller. Thats too big for what I'm doing. You are the guy that sold those 594nm KTP crystals on ebay a wile back? Can you tell me how many watts of IR can be pumped into them. Without saturating the crystal.

These crystals needed the vanadate, so they were sold at fire sale prices. The vanadate for 594nm is expensive and hard to find. :'(

I thought they only needed yvo4.

Will this beamspliter work with any wavelength?

lens coating: standard optical

so its got no coating making it work for certain wavelengths, but it wont perform as good as a specific wavelength one (more loss)

Aren't there small dichro's in the 803T sleds. I'm pretty sure that the small glass cubes in those sleds are dichro's. I have a whole bunch of them. phoenix77/rob You can also try EDMUND SCIENTIFIC, & I also found a bunch in the SURPLUS SHED, under 'BEAMSPLITTERS'

those are pbs cubes

laser wave has some of the best pbs cubes for combining like beams and dichroic mirror for joining mixed colors

i *just* wrote a bit about how to do that here:

combining two identical colors and then combining different colors will be different, the first with polarising combining, the latter with dichroic combining.

the cube heruursciences posted/sold is exactly the thing i wrote about too, as far as i can see. it works great for combining colors, indeed!

Yes- otherwise known as yttrium vanadate.

Y=yttrium VO4=vanadate ion

I think YVO[sub]4[/sub] , or yttrium orthovanadate needs to be doped with neodymium to form a crystaline structure of Nd:YVO[sub]4[/sub].Then , I don't know, I think it requires a special coating for whatever wavelenght you want to make the most of.
