Wish I could find a PBS beam splitter with a hole through it and see if I could coaxially combine three beams. The one going through the hole would need to be a much smaller beam diameter while the other two expanded. Would be kinda weird though, divergences wouldn't match.
I saw an old post at PL where someone wanted to find one of those, or have one made, but I don't know if they did or not.
This is the first time I have heard of this. Huh. It is always a good day when I learn something new. I'll have to check into this too. Thanks.
