Default WTB: 1122/1123, 1319, 1342 nm YAG Line & OC mirrors to produce yellow...

I've been looking on ebay as well as at some of the supplier web sites for mirrors which can be used with ND:YAG's for 1122/1123, 1319/1320 or 1342nm for use with a crystal to produce one of the yellow wavelengths, but cannot find them either used or new. If anyone comes across them, or a listing for them on a web site, please let me know.

If you see this post a few months from now please post any additional information you might have anyway. Often, I get kind responses to my WTB posts, go look and then don't see exactly what I need. If I have not replied I have found what I need, I'm still looking and could use your help. I would be interested in a non-functioning cavity with these mirrors if I can use the parts out of it. If you post and it is exactly what I need and able to order and receive it, I will donate an additional 20 bucks to the forum, or send the money to you, which ever. I've already spent a lot of time searching, not finding them yet.

Edit: I did find and buy some 1122nm OC mirrors for an inter-cavity LBO crystal to produce 561nm on ebay, but not the mirror for the back side reflector in a ND:YAG cavity, so interested in other manufactures mirrors too. I am making the assumption the back side mirror should be a line mirror, or selective for those wavelengths, maybe that isn't true for the back mirror?

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.

Default Re: WTB: 1122/1123, 1319, 1342 nm YAG Line & OC mirrors to produce yellow...

bumpity bump bump bump.....

To make 594 yellow, I've been told I need this:

Quote:
For you to make use of this (the yellow KTP and small diode pumped ND:YAG I have) you will need a lot of optics and spare time. You need a focus mirror TBHR 1064/1.31/594, a collimation lens for intracavity use or collimation mirror, another mirror HR at 45 deg 1064+ 1.31, and a final Hr for your rod at 1064/1.31. You'll want a heater for your KTP to stop it from favoring green, but if too hot and it favors red shg. The rod will need to be mounted to a copper heatsink or liquid cooled very creatively, but a least the 20W pump diodes are cheap.
Anyone see these items, please let me know

I have this 808nm diode pumped ND:YAG for 1123 nm to make 561nm yellow (lime) and need more optics for this project too:



I also have this KTP, LBO and crystal holder. I was hoping to be able to use the KTP to make 594 or 589nm with other optics, but the 561 nm LBO is the NL SHG crystal I have most of the optics for:

KTP:



LBO:




Crystal holder with a TEC built into it. I also have other similar crystal holders the above crystals can be mounted into:



This OC which I hope will work for me:



and this filter for the ND:YAG output to suppress 1064nm while passing 1123 nm:



With all of these, I think I just need a 1123 nm line HR for the back side of the YAG, or can I use a broadband mirror, due to having that filter? Also need another mirror for the back side of the KTP for intracavity SHG in an Y-fold configuration, but not sure what I need there, does anyone know if the mirror needs to be for both 1123 and 561nm on the back side of the KTP crystal?

This thread, the last post, shows the varia laser the ND:YAG came out of, as well as the 1122/23 nm filter and OC lens, shown above. With those parts I think I have a good chance of reproducing this in something smaller.

Thread link: 561nm Yellow YAG (?) from Lumenis Varia Eye Laser

Here is a photo from the above thread showing what I am trying to build, the center section is the 561 nm laser I want to build, the upper and lower are green and red.
