It sure is an impressive mounting system. How much did it cost?

Be careful not to thermal damage the ktp if you use two. You need to reduce the power density, which will lead to a larger beam profile.

He had it listed for over 700, been offering for two years every now and then, he always thought my offer was too low, but finally gave in and sold it to me for 2/3. I don't mind a larger beam profile, I will expand it to over 75mm anyway

Wow, what a good price for all that.
As for the 75mm beam and the possible 2-2.5w output, are you wanting to do lunar ranging or something.

Would be more worried about thermal damage in the YAG/YVO4 than the KTP.

Yes you do have to be careful with the yag etc, but ktp's are known for there low optical damage threshold. Using alonger focal length lens for the 808, should help combat both problems.

Yea, to yellow or not to yellow, that is the question. Not sure I can find what I need to make yellow, but on the lookout. If I do green, I have a 3mm x 17mm YV04 rod mounted in a heat sink but it is so long, I don't know if I can use the wavelength locked diodes with it or not yet.

I have been looking for the right YVO4 crystal for this, if I do go green, I just brought up this YVO4 off the cuff, had forgotten about it. Seller is not absolutely sure what coating, but believes from 808nm diode pumped system, maybe too long for that.

Default Re: 583.8nm and 589nm, the golden brothers

I'm guessing that it would be a standard 1064nm yvo4 as it is an Avia crystal. If so, it wouldn't be suitable for the 1342nm line.

OK, so pumped with 808 to make 1064nm? I bought it for that, not for yellow, just brought it up in case I can't use this thing for the yellow crystal.

Default Re: 583.8nm and 589nm, the golden brothers

That would be fine. If it isn't stated otherwise then it most likely wasn't worth stating. 1064 is the most common so it is unlikely that it would be something else instead. Have yourself a very nice green.

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

The most important thing to look for is a nd:yvo4 crystal coated for both 1064 and 1342. Depending on what you type in on eBay you might be able to locate one. You seem to have a lot more eBay luck than me.

I will probably need to find a supplier for that and pay $$$.

Default Re: 583.8nm and 589nm, the golden brothers

There is a reason why most of us haven't done it. They are not easy or cheap. The 594 is also less efficient than 589. But it will definitely be a great project.

If this crystal will work with greater efficiency at 589nm, I'd rather try to use a yellow which will produce the most power that is the most stable too (I'm assuming this might be the case for the higher efficiency). Maybe I should try to find a YVO4 with coatings for 1319 and 1064nm instead.

http://www.ebay.com/itm/112235093781



I paid 75 dollars, not $120. Ebay misrepresents the selling price when the seller accepts a lower buy it now price. The seller doesn't seem to know much about these crystals, maybe it really is very rare due to really being 594.3? Or maybe they got the wavelength wrong, I don't know. Also, I'm trying to find what high power means for this wavelength. Seller said they would see what additional info they might be able to get for me.
