Cooling and Trapping of Atoms with Laser Light sodium atoms to T = 2.4 × 10.K in a viscous molasses of photons tuned to the yellow “D-line” resonance of sodium. Potential optical traps are presented, and several ideas for cooling atoms to temperatures of 10.–10.. are suggested. Possible uses for ultra cold atoms are also mentioned.

Intra- and Intermolecular Energy Transfer of Large Molecules in Solution after Picosecond Excitationa tell us which modes interact by anharmonic coupling. The situation is different in large molecules. The number of vibrational quantum states rises strongly with the number of atoms and with the vibrational energy. The energy supplied to a specific vibrational state is transferred to numerous overt

Nonlinear Transient Spectroscopy with Ultrahigh Time-Resolution Using Light Sources with Controlled ltrafast transient spectroscopy by means of picosecond and femtosecond pulse technology undoubtedly brought about revolutionary development in this field of research.. There still remain, however, difficulties in the generation of practical light pulses and their applications in the time region far

Picosecond Modulation Spectroscopy in Sodium Vaporr. The time integrated four wave mixed signal modulates with increasing excitation delay with a period of 1.9 psec corresponding to the 6? splitting of the D lines. The modulation persists well into the region where the 7 nsec excitation pulses no longer overlap and far beyond the 100 psec correlati

Polarization Selective Detection of Hyperfine Quantum Beats in Cssurements of atomic level splittings in the GHz-range [1] In this contribution we report on the observation of fast coherent transients in Cs. Quantum-beats in forward scattering have been detected, which result from the hyperfine splitting of the ground and first excited 6p fine structure states. T

Observation of 517 Ghz Fine Structure Quantum-Beats in Nad in this contribution. For the first time quantum-beats, which are due to the fine structure splitting of the first excited electronic state in Na, have been measured. With a beat frequency of 517 GHz this is the fastest quantum-beat signal observed so far.

Measurement of First-Order Free-Induction-Decay in Csive devices. FID in Cs vapor is measured with picosecond time resolution, and for the first time beats due to the hyperfine splitting of the ground and first excited state with 9.2 GHz and 1.2 GHz can be observed on the fast decay curve.
