====== Jour Fixe ====== SS, WFP, PG, NJ, KZ ====== Atomslab ====== * Ernst and Nandan have agreed on more or less final form of the Bloch band paper outline and figures. * Ernst also wrote the abstract and now Nandan will start to write the paper. * Waldemar had atoms in the S-MOT, and will continue with the rest of the steps in loading to dipole trap. * The Wutz cavity is slightly misaligned that needs the incoupling to be readjusted. ====== Quench ====== * Looked at the beam from TA to fiber. Looks ok, but maybe will try another collimator. Efficiency is like 43%. * The lens position after AOM makes a difference in efficiency. Will go back to the cat eye design. ====== PTB/Meta-mirror ====== * Steffen worked completely last week on Metamirror project * Had a meeting with Ernst and again another meeting on 22nd. * Lost last week coupling of the mode in the cavity, again found the mode and measured again the ring down between 1535 and 1565 nm using reference mirrors. * There is a new laser that can tune over longer wavelength and has more power. * Preparing to present results in Uwe's group on next Tuesday: Metamirror results.
