Hi all!
Want to build high power rgb laser.
I've find several ways to combining multiple beams, say, knife edge & beam splitter techniques (once).

but... for example please take a look at KVANT 30w rgb:

How they obtain, for instance, 10W/445nm?? knife edge here?

the same for Red module: 10W/637+660nm etc

Any ideas about technique they use?

Many thanks!!

That's an arctos (sp?) Diode array. They knife edge multiple times then use a PBS to combine the two sets of beams. The three different wavelengths are combined with dichroic mirrors. Check out the reference guide on my website (in my sig)

Oh I see, I thought they used an advanced technique instead knife edging.
Thanks for your reply!
