Study of CPO resonances on the intercombination line in Yb
Pushpander Kumar, Alok K. Singh, Vineet Bharti +2
We study coherent population oscillations (CPO) in an odd isotope of the two-electron atom Yb. The experiments are done using magnetic sublevels of the $ F_g = 5/2 \rightarrow F_e…
Observation of coherent population trapping in a V-type two-electron system
Alok K. Singh, Vasant Natarajan
We observe coherent population trapping (CPT) in a two-electron atom---Yb---using the transition. CPT is not possible for such a…
Continuous beam of laser-cooled Yb atoms
K. D. Rathod, Alok K. Singh, Vasant Natarajan
We demonstrate launching of laser-cooled Yb atoms in a continuous atomic beam. The continuous cold beam has significant advantages over the more-common pulsed fountain, which was a…
Observation of the nuclear magnetic octupole moment of Yb from precise measurements of hyperfine structure in the state
Alok K. Singh, D. Angom, Vasant Natarajan
We measure hyperfine structure in the metastable state of Yb and extract the nuclear magnetic octupole moment. We populate the state using dipole-allowed transiti…
Optical frequency metrology with a Rb-stabilized ring-cavity resonator -- Study of cavity-dispersion errors
Alok K. Singh, Lal Muanzuala, Vasant Natarajan
We have developed a technique to measure the absolute frequencies of optical transitions by using an evacuated Rb-stabilized ring-cavity resonator as a transfer cavity. We study po…
Hyperfine spectroscopy using co-propagating pump-probe beams
Alok K. Singh, Sapam Ranjita Chanu, Dipankar Kaundilya +1
We have shown earlier that hyperfine spectroscopy in a vapor cell using co-propagating pump-probe beams has many advantages over the usual technique of saturated-absorption spectro…
