    Thanks for the info. The ND:YAG rod is special - low doping, un-doped rod ends and pumped at a wavelength below peak absorption, all to deal with the thermal lens problem when end pumping Nd:YAG at high power. It’s one of the reasons I’m really hoping to repurpose this system. I will be operating the laser well below max power.

    The rods look something (exactly) like this

    We've also got a handful of the pump diode stacks hiding in the back room. I really should get those listed.

    Nice! I would not have thought they would be on eBay, I should buy a spare. Looking forward to seeing the diodes listed.

    BTW, I typically give PL members a 20% discount if they order from me directly rather than through eBay.

    That’s great news and I will take you up on that. Let me know when you list the diodes.
