Doppler-free Selective Reflection spectroscopy of the transition of Cesium using a nanofabricated vapor cell

Armen Sargsyan, Rodolphe Momier, David Sarkisyan

Selective Reflection (SR) spectroscopy of the electric dipole transition of Cesium ( nm) is performed for the first time usin…

Blue laser induced bright red fluorescence in hot cesium vapor

Armen Sargsyan, Anahit Gogyan, David Sarkisyan

We have observed laser-induced fluorescence using 456 nm laser radiation, resonant with the 6S1/2-7P3/2 transition in Cs atoms. It includes red emission lines in the range of 580-7…

Observation of magnetically-induced transition intensity redistribution in the onset of the hyperfine Paschen-Back regime

Armen Sargsyan, Emmanuel Klinger, Ara Tonoyan +1

The Zeeman effect is an important topic in atomic spectroscopy. The induced change in transition frequencies and amplitudes finds applications in the Earth-field-range magnetometry…

Coherent Optical Processes on Cs D line Magnetically Induced Transitions

Armen Sargsyan, Arevik Amiryan, Ara Tonoyan +2

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

Circular dichroism in atomic vapors: magnetically induced transitions responsible for two distinct behaviors

Armen Sargsyan, Arevik Amiryan, Ara Tonoyan +2

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

Features of Magnetically-induced atomic transitions of Rb D line studied by Doppler-free method based on the second derivative of the absorption spectra

Armen Sargsyan, Arevik Amiryan, Emmanuel Klinger +1

We show that the Second Derivative (SD) technique of the absorption spectra of Rb atomic vapours confined in a nanocell with a thickness nm allows to achieve close…
