That was helpful thank you. I wonder if the transitions are that tight or if you can temp tune the sum difference frequencies. I have tried sum difference only once and it failed.
I get confused on these yellows 589 591 593 594. Without seeing or measuring I don’t think you can really know from a picture. Still pretty good color.
Has anyone heard from him? I wonder if he might offer a fresh batch? If not I would think it should not be too hard to trace and copy the circuit unless he has a micro like the flex mod
That would make a great data link through an 8” telescope. Also at 8w it is 444nm which is perfect for Py pumping.
A dual folded end pumped cavity could get 16W pump and likely make 2-3W red. That’s OPSL territory.

He showed up. He has said he will make good. All those outstanding should state they were made whole and we can move on. I love the yellow I got. In fact I’d like some more. Tinker dude make it so. Maybe some of us can even help you get going just ask for help.
I’ll pull the paper. It’s not a big deal alignment. Mm1 should be fine. The reflector is a facet of a separate fiber. It pops on with a standard connector. The real problem is the beam is very divergent.

I have no issue with sell threads. Why not just have a section just like group buys. Sure someone will get scammed but that happens on Craigslist and eBay too. Let the forum get a cut!
I have an ILT500mw unit that says otherwise. If I don’t run it at least twice a year it takes days to get it back.
Mixed gas would know best but I have not seen him here in a long time
Water jet is the best solution. We have one at the university. I have a slab of marble. I’ll let you know how it goes. We can cut stone like butter. I forgot we have it. I think it can cut like 2” deep. Tell me the size you like and I’ll try it out. This works for sure I have seen it...
No hurry. More is better. I just got email Dy fluoro fiber is back in stock 500 a meter. You need 1.8m to do the 445 pumped 575nm yellow fiber laser. Bit rich for my tastes but you get 1.2W off an 8w pump. All it requires is a 4% OC and a facet reflector. You pump through the OC. You focus...
I do similar but with a yellow opsl and and blue opsl. The resulting white has to be seen to appreciate. What is LEP?
LEP stands for laser-excited phosphor and is an exciting new solid-state lighting technology more powerful and efficient compared to LEDs.
Google is your friend! Yea I have...
Why bother with this. Just buy a 100w CO2 laser and mount in a handheld box or a 1kw fiber laser.
I am being sarcastic. This kind of stuff is just stupid dangerous. Watch the videos and live through them.

Likely blue laser pumping a yellow,phosphor coupled into a fiber. A microscope illumination source or reflection standard
I’m going make this up so……
Cut the marble on a rock saw to eight sides or more. Ie as round as possible to start. Drill a hole as centered as you can. Insert a metal rod dipped in expoxy and let it dry. Place in a lathe or large mounted drill. At moderate speed push a piece of abrasive...
