I have ovens for some of my SHG crystals as well as controller boards for them on the way now. I also have 806-810 FAP800's with focusing lens assemblies with SMA couplings on them to make the interface easy, TECs and temperature control boards for the FAP as well as high power YVO4 crystals in mounts with both water and TEC cooling, so will have some combination to try, not sure which first. Most of these parts have come out of Coherent Avia lasers.
Oh, I was talking about the new ones, not the used eBay ones, though those are way cheaper. Same boat though, I don't want to gamble on one of those.I have been looking at those China ones, they are cheaper but I haven't been willing to risk buying them, almost always have wires chopped short out of some equipment and knowing how cheap the chinese are, likely end of life or worse. These were also removed due to end of life, I suspect, but each diode was checked to make sure they appeared to produce plenty of output. I don't want to use them at full average power though, so no matter. Need to find a QCW driver for them though.
