Bose-Einstein condensation of alkaline earth atoms: {Ca}
Sebastian Kraft, Felix Vogt, Oliver Appel +2
We have achieved Bose-Einstein condensation of Ca, the first for an alkaline earth element. The influence of elastic and inelastic collisions associated with the large groun…
The optical calcium frequency standards of PTB and NIST
U. Sterr, C. Degenhardt, H. Stoehr +7
We describe the current status of the Ca optical frequency standards with laser-cooled neutral atoms realized in two different laboratories for the purpose of developing a possible…
Wavelength dependent ac-Stark shift of the 1S0 - 3P1 transition at 657 nm in Ca
Carsten Degenhardt, Hardo Stoehr, Uwe Sterr +2
We have measured the ac-Stark shift of the 4s2 1S0 - 4s4p 3P1 line in 40Ca for perturbing laser wavelengths between 780 nm and 1064 nm with a time domain Ramsey-Borde atom interfer…
Photoassociation spectroscopy of cold calcium atoms
C. Degenhardt, T. Binnewies, G. Wilpers +4
Photoassociation spectroscopy experiments on 40Ca atoms close to the dissociation limit 4s4s 1S0 - 4s4p 1P1 are presented. The vibronic spectrum was measured for detunings of the p…
