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…
Saturated-absorption spectroscopy: Eliminating crossover resonances using co-propagating beams
Ayan Banerjee, Vasant Natarajan
We demonstrate a new technique for saturated-absorption spectroscopy using co-propagating beams that does not have the problem of crossover resonances. The pump beam is locked to a…
Precise frequency measurements of atomic transitions using a Rb-stabilized resonator
Ayan Banerjee, Dipankar Das, Vasant Natarajan
We demonstrate a technique for frequency measurements of atomic transitions with a precision of 30 kHz. The frequency is measured using a ring-cavity resonator whose length is cali…
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 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…
Precise frequency measurements of the D-lines and fine-structure interval in K
Ayan Banerjee, Dipankar Das, Vasant Natarajan
We use a diode laser locked to a Rb transition as the frequency reference along with a scanning Michelson interferometer to make precise measurements on the and lines o…
