Cooling and trapping Strontium atoms
We performed the simultaneous trapping of two isotopes (86Sr and 88Sr) in the red MOT (N.Poli et al. Phys. Rev. A 71, 061403(R) (2005)). Thanks to the low temperature obtained in the red MOT, such isotopic mixture is efficiently transferred into a FORT. We observe fast interspecies thermalization in the dipole trap which allows one to set a lower bound of 70aB on the 86Sr-88Sr elastic cross sec...
متن کاملElectromagnetic trapping of cold atoms
This review describes the methods of trapping cold atoms in electromagnetic fields and in the combined electromagnetic and gravity fields. We discuss first the basic types of the dipole radiation forces used for cooling and trapping atoms in the laser fields. We outline next the fundamentals of the laser cooling of atoms and classify the temperature limits for basic laser cooling processes. The...
متن کاملLaser Trapping of Radioactive Atoms
Light forces acting on radioactive atoms confine them in very dense and cold samples achieving large phase space density. We describe the processes of radioactive atom production, reduction of their velocity and capture. The trapped atoms form excellent sources for the study of atomic parity non-conservation, β decay asymmetry, other weak force processes, and α decay asymmetry.
متن کاملMagneto - Optical Trapping of Chromium Atoms
We have constructed a magneto-optical trap for chromium atoms. Using trapping light at 425 nm and two repumping lasers tuned to intercombination transitions, over 10 atoms were trapped and average densities of over 10 m were obtained. Non-exponential loss of atoms is observed at high densities indicating inelastic collisions between trapped atoms. Over a range of trapping conditions, the densit...
متن کاملTrapping of single atoms in cavity QED
By integrating the techniques of laser cooling and trapping with those of cavity quantum electrodynamics (QED), single Cesium atoms have been trapped within the mode of a small, high finesse optical cavity in a regime of strong coupling. The observed lifetime for individual atoms trapped within the cavity mode is τ ≈ 28ms, and is limited by fluctuations of light forces arising from the far-detu...
