Stimulated Raman adiabatic passage in sodium vapor with picosecond laser pulses

Stimulated Raman adiabatic passage in sodium vapor with picosecond laser pulses Experimental measurements and calculations of stimulated Raman adiabatic passage transfer efficiencies were made on a sodium gas starting from the 32S1/2 electronic ground state, passing through the 32P1/2 and/or the 32P3/2 to the 52S1/2 state. The lasers used in the experiments had a pulse width of several picoseconds and were close to the Fourier transform limit. Although the linewidth of the laser was much smaller than the spin orbit splitting between the 3P1/22 and 3P3/22 states, Experiments and calculations reveal that both 3p states play a role in the transfer efficiency when the lasers are tuned to resonance through the 32P1/2 state, revealing evidence of quantum interference between the competing pathways. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review A American Physical Society (APS)
