Abstract

We describe in this paper a fast and efficient method of producing a high density of barium (Ba) atoms in the¹D₂metastable state, which is a candidate initial state for a new class of cooperative and coherent optical process called paired superradiance (PSR). In the experiment, Ba atoms are excited first by laser light to the¹P₁state and then brought to the desired state¹D₂via radiative transition in the superradiance (SR) mode. It is found that a production efficiency (from¹S₀to¹D₂) of more than ∼30% is achieved within a time interval of a few nanoseconds for a Ba density n > 1019m^-3. Several key features of SR important for future PSR experiments are also studied.
