Modern measurement techniques and setups<\/h1>\n\n\n\n

None of our scientific results could have been possible without advanced experimental setups and modern measurement techniques. By implementing new solutions and concepts, we have significantly contributed to the technological development of ultracold physics and beyond. We have advanced state-of-the-art ultracold gas systems<\/strong> [1], and developed multi-frequencies laser injection techniques [2], original magnetic field compensation methods [3], and new pump-probe spectroscopic methods [4]. We also investigated laser cooling per se<\/em>, showing the quantum nature of Doppler cooling on narrow transitions [5], and investigated cooling on electric quadrupole transitions [6].  <\/p>\n\n\n\n
