Adiabatic passage in three levels closed-loop systems with chirped lasers pulses

Year: 2025

Type: article

Abstract: This study demonstrates complete adiabatic population transfer in a closed three-level atomic system using chirped laser pulses. By satisfying the three-photon resonance condition, we effectively mitigate the first-order Doppler effect. Under the assumption of weak coupling between the stable levels, we show that relative phase fluctuations of the lasers exert a negligible influence on the population dynamics during the transfer process. A comprehensive analysis of the system parameters is conducted to determine the optimal conditions for achieving 100% population transfer while minimizing the excited state population
