I contacted Vescent about the [[Vescent Family|laser controller]] problems we've been having, and it turned out to be an issue that would arise when the PID settings for the temperature controller weren't quite right. I retuned it and it's working much better now.
Replaced the 400 mm lens that focuses the 780 before the cavity with a 500. Had to completely re-align the 780, but 633 generation is higher again with an efficiency of ~<math> 7*10^{-7}</math> I ordered a 750 mm lens from Thorlabs which might work better too. There are definitely still gains to be made from having the 780 better collimated/focused, but I think it's good enough now to take the data we want.
