Parametric Study of CPT Resonance in Rubidium Vapor Cell for Application in Atomic Clock Indian J. Pure Appl. Phys. (IF 0.7) Pub Date : 2022-06-10 Rajaiah Kaitha, Manjula R, Pragya Tiwari, Minni J Kappen, Shubhajit Biswas, Bijoy Raha, Swarupananda Pradhan, Venkatappa Rao Tumu, Umesh S B, Elumalai S, Kalpana Arvind P, Sriram K V, Prashanth C Upadhya
The performance of Coherent Population Trapping (CPT) based atomic clocks primarily depends on the characteristics of CPT resonance. We have performed experiments to study and optimize the characteristics of CPT resonance in 87Rb atoms by measuring its contrast and full-width-at-half maximum (FWHM) as function of laser excitation and temperature of atomic vapor cells with different dimensions. A four-level
