(Heidelberg [u.a.] : Springer, 2021)
    Methods and techniques are described for automated measurements of greenhouse gases (GHGs) in both the laboratory and the field. Robotic systems are currently available to measure the entire range of gases evolved from ...
  • Efficient magneto-optical trapping of a metastable helium gas 
    Pereira Dos Santos, F.; Perales, F.; Léonard, J.; Sinatra, A.; Wang, J.; Pavone, F.S.; Rasel, E.; Unnikrishnan, C.S.; Leduc, M. (Les Ulis : EDP Sciences, 2001)
    This article presents a new experiment aiming at BEC of metastable helium atoms. It describes the design of a high flux discharge source of atoms and a robust laser system using a DBR diode coupled with a high power Yb ...
  • Phase matching of high-order harmonics in a semi-infinite gas cell 
    Steingrube, Daniel S.; Vockerodt, Tobias; Schulz, Emilia; Morgner, Uwe; Kovačev, Milutin (American Physical Society, 2009)
    Phase matching of high-order harmonic generation is investigated experimentally for various parameters in a semi-infinite gas-cell (SIGC) geometry. The optimized harmonic yield is identified using two different noble gases ...
