white beam with NO dichros?

[-bart-]

Costs aside, what efficiency would be achieved, and would beam parameter product be preserved ?

[shrad]

wouldn't a fiber of say, 1 to 2mm core diameter and the same diameter decreasing slowly over length, to achieve one or two meters of 400µ core to combine more efficiently (several turns around a pillar) work?

some kind of half-hyperbolic lightpipe... (please credit me if this has never been used or thought of before )

[-bart-]

They're called tapered fibres iirc.

[planters]

I am not certain, but I believe that a tapered fiber solution produces loss proportional to the taper. This is consistent with the law of increasing entropy. Otherwise you could take some crappy multimode beam tuck into a large diameter entrance and taper it, even if ever so gently, down to a 1 um spot for collimnating.

Who makes up these laws, thats what I'd like to know?

If we could just stop them making them up, we'd be home and dry!

What if we went to Congress tomorrow and told them to drop Newton's altogether? I mean, inertia is a bitch....

Warp speed, Mr. Sulu.

[planters]

Actually inertia and friction are both pretty nice.

Ok, Some things I just will not give away.

Ready to sign a NDA?

No. If you have some interesting ideas go ahead and share them. Otherwise this sounds like Coherent. With enough money you can do almost anything, but that's not very rewarding. What kind of approach are you looking at.

Whats wrong with Coherent?

When your 40, looking for a wife, looking at adopting a kid, your attitude towards "giving it away" will change. I have documentation that it works, and that was hard to come by. I've been doing this for 20 years. I do like to get paid once in a while.

Neat problem for me, if I post a "fraction" of the details, some one here will clone it. I'm probably the champion "Giver Awayer" on this forum because I love the industry. But if its cutting edge, I'm keeping it.
