Default Grow your own KTP crystals?

Has anyone entertained the idea of growing their own KTP crystals? I wonder how difficult it really is.

Ummm, i gather it would be VERY VERY VERY difficult, seeing is KTP is a mixture of different crystals and coatings, i think
?

I meant potassium trihydrogen phosphate, but no matter.
Even tho the growing process and the fabrication into useful devices are likely beyond the grasp of most of us, I don't like being told that I can't.

Well obviously you can make them. I mean, its not a lie, they exist because they were made. ;D

But yeah, seriously, might be hard and expensive.

Probably like making your own green laser from components:
possible but a serious pain in the rear, and with a huge amount of luck you might squeeze a few percent efficiency out of this.

On the other hand, that is probably how they started in the beginning - lousy crystals that were continuously refined until today you get some very fine lasers.

I'd say, go on and try it, maybe you will discover a crystal that will emit a pink and blue line when injected with 650 nm

Yes. That's the idea. I'd be quite content to get just that far! Patience, repetition and luck should provide such an effect.

Well, how was milk from cows discovered in the first place? Somebody must have had that crazy idea of sucking on those four weird contraptions (who knows, maybe additional members ?!?) hanging down from a savaged animal!

Maybe that way, other colors will be discovered.
(not by sucking on an utter, but by going unconventional ways, of course!)

Now you have me thinking if anyone's tried milk as a lasing medium! Probably only works with some rare Yak's secretion.

I believe that to lase cow's milk you would need crystals of Molybdenum Oxide... or um... MoO for short. ;D

Of course, if you're talking integrated cow's milk lasing you may end up with a modded bovine laser show like this...

I don't know if milk is transparent at any usable wavelengths.

No you don't. You mean potassium titanyl phosphate.
