Laser cooling and trapping of Yb from a thermal source
Umakant D. Rapol, Anusha Krishna, Ajay Wasan +1
We have successfully loaded a magneto-optic trap for Yb atoms from a thermal source without the use of a Zeeman slower. The source is placed close to the trapping region so that it…
Precise measurement of hyperfine intervals using avoided crossing of dressed states
Umakant D. Rapol, Vasant Natarajan
We demonstrate a technique for precisely measuring hyperfine intervals in alkali atoms. The atoms form a three-level system in the presence of a strong control laser and a weak…
Precise fine-structure and hyperfine-structure measurements in Rb
Ayan Banerjee, Dipankar Das, Vasant Natarajan
We demonstrate a new technique for measuring the absolute frequencies of atomic transitions. The technique uses a ring-cavity resonator whose length is calibrated using a reference…
Observation of sub-natural linewidths for cold atoms in a magneto-optic trap
Umakant D. Rapol, Ajay Wasan, Vasant Natarajan
We have studied the absorption of a weak probe beam through cold rubidium atoms in a magneto-optic trap. The absorption spectrum shows two peaks with the smaller peak having linewi…
Sub-natural linewidth in room-temperature Rb vapor using a control laser
Umakant D. Rapol, Ajay Wasan, Vasant Natarajan
We demonstrate two ways of obtaining sub-natural linewidth for probe absorption through room-temperature Rb vapor. Both techniques use a control laser that drives the transition fr…
Loading of a Rb magneto-optic trap from a getter source
Umakant D. Rapol, Ajay Wasan, Vasant Natarajan
We study the properties of a Rb magneto-optic trap loaded from a commercial getter source which provides a large flux of atoms for the trap along with the capability of rapid turn-…
