NJ took measurements for non-linear AC Starkshift
All data together does not fit that well → caused by lattice waist change due to moving the lattice inbetween? lockpoints of lattice change the waist-/position?
Hyperpolarizability causes non-linear shift which can be measured and is outside the errorbars
WFP had some issues getting spectroscopy signal with SWAP-sequence → under investigation
Shutter for SHG 2 gave some problems → solved
