Jour Fixe

WFP, PG, SS, NJ, kHz

Pia wants to do her B.Sc at Mg Atomslab (January).
- Meeting with her Wednesday 14-15h

Replaced L4
T-MOT and DT working with replaced L4 now
- Frequency instabilities of the previous L4 now solved
Investigate the power instability of L2/AOM this week
Also continue with Nishads measurements for his thesis
Quench system
- Fiber coupling efficiency is bad right now → To be adjusted (10mW → 100 µW)
Magic System
- Changed lense to SHG coupling → 1.5 W
- Infront of fiber: 1.1-1.2 W
  - Seems to be limited by stimulated brillouin scattering at ~ 1W. Fiber output limited to around 650 mW
Money discussion with Ernst today - What to buy?
- Replacement of L2 system?
  - Toptica?
  - Stefan Hannig SHG?
