ResLab:
Clocklaser (R1) is running fine; Outer Shield Temperature decreased by 20 mK for higher control range at 13.09. due to an instability at this time
Frequency Comb is locked, but Beat signal is quite low → Maybe new pump diodes necessary
Reference Resonator (R2) broad linewidth problem: most probable dirt / oil on mirror from turbo pump maybe; EOM?
Maser available from 30.09. on

Hannover Beast:
Vacuum pressure necessary: 10^-8; Stability \ fluctuations needed in the order of ~ 10-10 for 10-18 freq. instability
Mechanical Stuff almost ready, some screw holes have to be done; orders for vacuum stuff almost ready
Mirrors will be transferred soon to PTB

Wettzell Laser:
Outcoupler mirror with 25 % reflectivity
Piezo is glued → The ECDL resonator is ready
Fiber coupled, efficiency ~ 25 %; new outcoupler lens: 65 %; adjusted through the isolator
lens will be glued then
Old power: ~ 35 mW @ 170 mA
Powers now up to
Wavelength of 632,811 nm @ 100 mA
Temperature control ready \ Dual Meerstetter for baseplate & Laser diode
AOM breadboard not ready within 2 months
Waldemar can begin writing his thesis, put AOM breadboard into outlook; linewidth and stability measurement would be nice
HiWi contract until december; maybe stop it earlier
breadboard setup almost done, orders for AOMs prepared

Nandans FACT Meeting: Met Peter Wolf, spoke about paper, & Kurt Gibble → Paper discussion

AtomLab:
Scan over line @ 13.09.
Another pair of MOT coils → seems to be better, 15 Gauss B-field
Photomultiplier used; most efficient # (count) sensor;
new magic wavelength measurement has to be done \ already AC Stark measurement done
carrier lw 400 - 1500 Hz
Ti:Sa problems, Autotune works nice, 3 mK temperature differences
degradation of mwl lattice windows, but enough power available
shortest pulses: 10 µs; with new pulse box even shorter

Open questions:
What is the lw in a deep lattice? (from the last meeting)
→ hard to say…
What is the reason for broad linewidth of R2?
Maser for how long?
