摘要
We explore the possibility of decelerating and Doppler cooling an ensemble of three-level Lambda-type atoms by a coherent train of short, nonoverlapping laser pulses. We show that Lambda atoms can be Doppler cooled without additional repumping of the population from the intermediate ground state. We derive an analytical expression for the scattering force in the quasi-steady-state regime and analyze its dependence on pulse-train parameters. Based on this analysis we propose a method of choosing pulse-train parameters to optimize the cooling process.
