====== Jour Fixe ====== NJ, PG, WFP, kHz ==== Atomslab ==== * TiSa SHG * Toptica does not tell anything about the waist in the cavity * Tried different incoupling lenses, but ended up to either end of the alignment * 1.3 W @ f=100mm * Outcoupling beam cant kept symmetrically * Probably first collimation lense not perfectly collimating -> You can't get the beam symmetrical over all beampath with the prism * It is crucial, to have the beam well collimated, since you can't compensate for an astigmatism with the prism. * Build a spare laser for L4 but in Littrow configuration * SWAP experiments * With SWAP light -> Number of atoms still go down (7.5 µW, 20 MHz detuned) * Going closer to resonance, line becomes narrower * Atomcount in the DT are low: TMOT? * Quench * Power optimized: Back to 40 mW infront of fiber * Now working on frequency stabilization and tuning it to resonance ==== Reslab ==== * SS + NJ got the comb back working * Good modelock point * Next: Coupling to new PCF
