Optical vortices, which are beams with spiral‐shaped wavefronts and screw phase
dislocations, have potential for supporting high‐capacity optical communications. In this …

We have investigated electromagnetically induced transparency (EIT) in the spectrum of
selective reflection at the interface between Rb atomic vapor and a dielectric nanocell …

To reliably register the absorption or selective reflection of laser radiation in a nanocell filled
with a vapor of Cesium or Rubidium at thicknesses below 100 nm, it becomes necessary to …

Atomic transitions of alkali metals for which the condition F e− F g=±2 is satisfied have null
probability in a zero magnetic field, while a giant increase can occur when an external field …

The increased spectral resolution allowed by the use of extremely thin vapor cells has led to
the observation of interesting behavior of alkali transitions when placed in a magnetic field …

Atomic transitions satisfying F e− F g= Δ F=±2 (where F e stands for excited and F g stands
for ground state) of alkali atoms have zero probability in zero magnetic field (they are so …

$^{39} $ K atoms have the smallest ground state ($^ 2S_ {1/2} $) hyperfine splitting of all the
most naturally abundent alkali isotopes and, consequently, the smallest characteristic …

In this work, magnetically induced (MI) transitions of the Cs atoms in strong magnetic fields
up to 6 kG, and their applications in spectroscopy are studied experimentally and …

It is demonstrated that the use of a micrometric thin 39 K vapor cell (MTC) and saturated
absorption (SA) spectroscopy allows the formation of narrow atomic lines in the transmission …

Differential single-beam saturated-absorption spectroscopy (DSSAS) is proposed to
stabilize lasing frequency and suppress Doppler-broadened background and common …
