This thread is for the discussion of all things related to solid-state lasers. Solid State lasers are a class of laser utilizing paramagnetic ions, color centers, and organic dye molecules suspended within solid amorphous or crystalline materials as gain media. Although semiconductor lasers...

That would eliminate 1064nm (or 1319nm depending on the angle) though, so it would only work with separate crystals.

Sorry to kinda derail this thread again, maybe we need to start a DPSS general thread. Anyway, Alaskan, if you want 589nm out of this it's going to be a real challenge. Since it's going to be operated in a pulsed mode, you want an NLO crystal with a large phase-matching bandwidth. Also, you...

That's either not DPSS or not 5.5W. What wavelength is it?

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Let's not forget that it also likely requires 3-phase power.

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please And just like that, the eBay thread has turned into a discussion on the nature of reality.

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Alright Copi, calm down. It's just a common expression that has for some reason become associated with Carl Sagan. In this specific example it holds well, for if we hadn't investigated alternative medicine...

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please The thing about science is that it is intrinsically a self-correcting mechanism. When something is proven incorrect, it is discarded, or at the very least reassessed. There is no emotion or "but I want that to...

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Well of course it's a scam, but these pseudoscientific "cures" and whatnot have been around forever. The only difference is now these people can throw a lot of technical jargon in there so that people...

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please What is it with these kinds of things and water clusters? Vogel crystals too...

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Don't calibration lights get connected optically via fiber?

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please You Need a PCI slot for a special card: As Alaskan pointed out, this can be a huge PITA because most modern computers only have PCIe.

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Ocean Optics INC. S2000 Fiber Optic Spectrometer w/ Cable

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please They're planar though. It's stupidly difficult to get planar-planar resonators lasing (near impossible) unless your system is so powerful that you can use thermal lensing to your advantage. Might be good for...

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please You'd be extremely lucky to get an optical-to-optical conversion efficiency of >~40% for an amateur laser.

First off, welcome to the forum! :) Specifically, what are you looking for? Do you want to burn stuff, pop balloons, point out stars, learn about optics, or something else? Yes and no. Green is the perceived to be the brightest by our eyes, but in terms of actual intensity, a 1W blue laser...

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please I'm just waiting for this to be legit and for everyone to consecutively lose their minds when it turns out to be overspec. :crackup:

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Well if a short 1-B tube can lase orange with a 612 OC and a broadband HR, then you should be able to get something of it with the optimal optics.

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Might be interesting to see if Sam has any 612 HRs/OCs to see how much orange you could get out of it. Eh, if it stays up for long enough I might have to make an offer. Damn this hobby. Lol, it looks like...
