High-resolution hyperfine spectroscopy of excited states using electromagnetically-induced transparency
Anusha Krishna, Kanhaiya Pandey, Ajay Wasan +1
We use the phenomenon of electromagnetically-induced transparency in a three-level atomic system for hyperfine spectroscopy of upper states that are not directly coupled to the gro…
Precise measurements of UV atomic lines: Hyperfine structure and isotope shifts in the 398.8 nm line of Yb
Ayan Banerjee, Umakant D. Rapol, Dipankar Das +2
We demonstrate a technique for frequency measurements of UV transitions with sub-MHz precision. The frequency is measured using a ring-cavity resonator whose length is calibrated a…
Precise measurement of hyperfine structure in the state of Rb
Umakant D. Rapol, Anusha Krishna, Vasant Natarajan
We demonstrate a technique to measure hyperfine structure using a frequency-stabilized diode laser and an acousto-optic modulator locked to the frequency difference between two hyp…
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…
