Focal scan
We have a very non-ideal laser focus (see elog)
peak intensity during the z-scan looked okish
outside the focal plane the spot becomes messy
after optimizing with the beam shaper
KES
Step 1: find vertically
Step 2: find horizontal position
EOS Timing
- First scan
There is a weird background signal that is of the same order as the actual EOS signal which we clearly saw.
