“Stimulated Raman adiabatic passage”的意思、由来-开放百科全书

Stimulated Raman adiabatic passage (STIRAP) is a process that permits transfer of a population between two applicable quantum states via at least two coherent electromagnetic (light) pulses.^[1]^[2] These light pulses drive the transitions of the three level Ʌ atom or multilevel system.^[3]^[4] The process is a form of state-to-state coherent control.

Population transfer in three level Ʌ atom

Consider the description of three level Ʌ atom having ground states

and

(for simplicity suppose that the energies of the ground states are the same) and excited state

. Suppose in the beginning the total population is in the ground state

. Here the logic for transformation of the population from ground state

is that initially the unpopulated states

and

couple, afterward superposition of state

and

couple to the state

. Thereby a state is formed that permits the transformation of the population into state

without populating the excited state

. This process of transforming the population without populating the excited state is called the stimulated Raman adiabatic passage.^[5]
