Hyperfine measurement of state in using double resonance on blue and IR transition
Elijah Ogaro Nyakang'o, Dangka Shylla, Vasant Natarajan +1
In this paper, we present the spectroscopy of 6P state in Rb using double resonance technique at and . The double resonance technique…
Generation of a cold pulsed beam of Rb atoms by transfer from a 3D magneto-optic trap
Sapam Ranjita Chanu, Ketan D. Rathod, Vasant Natarajan
We demonstrate a technique for producing a cold pulsed beam of atoms by transferring a cloud of atoms trapped in a three dimensional magneto-optic trap (MOT). The MOT is loaded by…
Absolute frequency measurements of the line and fine-structure interval in K
Ayan Banerjee, Vasant Natarajan
We report a value for the -line frequency of K with 0.25 ppb uncertainty. The frequency is measured using an evacuated ring-cavity resonator whose length is calibrated…
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…
