You are correct. And because it as far as I've been told is required for the process. A regular KTP doesn't work because it's efficiency is too low from the irregular structure. Periodically poled one can have up to 20x the efficiency.

LOL I read your initial message and went to google about possibilities of KTP.
Just for the record: KTP can be used with Nd:YAG like these people did
Laser-diode Array Pumped Nd?YAG/KTP Continuous Wave 589 nm Laser with Intracavity Sum-frequency Mixing--?Acta Photonica Sinica?2005?09?

That ppKTP is more efficient I knew. It should be more expensive to make it, and I wondered if ppKTP started to be used in pens too.

Your built may create a new star

Check if it has a periodical pattern on its surfaces.

Interesting note, was looking at these crystals and I just realized something...I don't think this is a YAG. Its not purple....its green. thoughts?

I still have to say this.

It's amazing that a small crystal has the power to change light. I mean, when you come to think of it that's pretty amazing

It will always amaze me at least, don't know about you all

Can you see any indication of it being 2 crystals?

Also....Green? Wha...Huh? Wouldn't that mean its Nd:YVO4? I thought 589 was Nd:YAG

I'm sure its not an yittrium ortho vanadate....but if its a YAG it must have a very low dopant level... Neodymium as a dopant gives off a purple-pink color. its very pretty...but this is more of, for lack of a better way to describe it, more of a flouride pale-green color. it just suddenly hit me today..."Wait a minute....Why is this thing not purple?!"

Yea, because Nd:YVO4 doesn't have the two needed lines for 593.5. Two crystals, a YAG and a vanadate? what the heck is that thing

Answer: Gypsy magic.

Or CNI found something with an 1187 line lol

Now this might be an idea. As it is a single crystal i'm positive, but it certainly is puzzling. I'm very curious now. I may have to bust out my book on lasing mediums and the good ol' internet and see what they've been smoking to come up with this! (and this is a 589nm not a 593.5nm laser so it would be 1178)

Default Re: Disassembly of a 589nm laser PGL-III-A (PIC HEAVY)

It would be cool if you make a TEC cooled set up, see how much power you can get out of the set


Also, random side note, but it looks like there are 2 drivers- am I correct in assuming one is just the standard driver, while the other is responsible for the pulsing?

If they are what I think they are, I should be able to get over 50mW in theory if I had a strong enough pump, good alignment with low waste, and a little luck. I am considering rebuilding it, but I don't have time lately. If I do I'll be sure to share though.
