Will any of the diodes from this new batch be up for sale? The fact that heat plays such a factor is very pleasing for me. I'm planning to get as close to 500nm as possible at room temp, and use that diode in a TEC housing. I think I can bring it down to 498nm-ish if I can keep the...

Aloha broha, I am also very interested.

Well...I am certainly very interested. I've got an area picked out to set my lab up once I move, and tunable lasers have always been a joy of mine. This looks like a quality way of breaking in the new space.

Has anyone plotted the impact that temperature has on blue shift? As in, how low do these things need to go for a 5 or 8nm shift?

Yes, hi; hello? 505nm? My excitement is very yes. I'll be watching as this develops and buying the first 505nm diode that hits the market... What a time to be alive.

Well...this has been a decent read. It's a been a while since anyone's tackled a CVL, or even an MVL of any kind for that matter. Kudos, and well done. I cannot wait to finally move and have the space to get my hands dirty again..

>Horridly efficient >Output coupler isn't even mirrored Regardless of efficiency concerns, the sheer volume of light production regardless of its efficiency, is massive. Very, very, very soon, I will actually have a decent lab area for 2, perhaps 4 years. I am using this as my inspiration to...

Oh my; well this is certainly a refreshing addition to the gas sub-forum. Well done, mate. :beer:

It's 609.6 or 609.07 that we are deciphering between. Gas Lasers references 609.6nm, as does a source that Steve was mentioning to me. Some Russian paper on line competition with 632.8nm - 609.62nm was mentioned with some interest, but nothing more. The plan was simple, use optics that would...

We aren't worried about contaminants. There is a real noted He-Ne line at 609.62nm that will cause competition with 632.8nm when present - nothing to do with contamination that I know of.

604nm has nothing to do with yellow.. 604nm is made via 445nm pumping Pr:PAYAC. Pr resonates at the low 600nm spectrum. The wavelength is determined by the lattice. Much like Nd:YAG lases 1064nm but Nd:YLF resonates at 1047nm and 1053nm; Pr:PAYAC lases at 604nm but Pr:YLF lases at 607nm.

In short, Sam and I (and likely Steve without him realizing it) need everyone with 609nm lasing to self-identify here. Preferably with some recent imagery of the line in question visible. We have some theories that we need to test, and in doing so, we need two things. 1. All known owners of...

Well this is certainly interesting... Considering the left-most line has a "halo" around the central spot, and they flicker, that almost tells me that your mirrors aren't matched perfectly with the divergence of the gain output. You'll find this with gas units as well, instead of all the light...

I'm certain that it's Laser Physics, fairly that it's a Reliant. As for 300, I don't have the expertise with this maker to know for sure. Even some Ar+ will give that full ion spectrum warning just to make the process easier on the company.

I can't guarantee the reliability of this information, but I know it's a group a lot of the "founding fathers" of lasers used to frequently post on, before it slowly died like everything else on the internet. I'll keep sifting and see if I can't find anything that supports or contradicts it...

Thought we all agreed to just let the dust blow over on DTR's side before getting involved? Oh well, what's done is done.

Any updates? Good, bad, or ugly? I'm not expecting diodes at this point, but I at least want to make sure all parties are being held equally accounted for.

Not the best outcome so far. What is the window for PayPal disputes? Since your agent has been working with you on this, do you think she'd be willing to stretch the rules a bit? $750 in the black, I assume, isn't a terrible dent for someone as established as you are. However, it's about the...

I get 1130nm as lasing from Yb:YAG, however, Yb:KGW lists 1023-1060nm. This isn't terribly extraordinary. It's just like the differences in peak emission of Nd dependent on the lattice it's in; YAG vs YVO4 vs Glass vs Etc Etc... As for the YLF, oh yeah, it'll be costly. I told them I don't...

So Yb-Fiber. I'd totally forgotten about doped fiber. That stuff is just beautiful... Wonder if a crystal lattice of Yb rather than fiber, would still work. The upside to fiber rather than a rod, though, is you have a MUCH longer gain medium to produce the wavelength you're looking for. A...
