Description
Using laser pulses to manipulate the internal quantum states of atoms and molecules provides new opportunities to create novel quantum devices. Coherent population transfer is the fundamental tool for many potential quantum applications such as atomic lithography, Rydberg arrays, and quantum information processing. We describe the Rydberg state excitation in a three-level system through Stimulated Raman Adiabatic Passage (STIRAP) and an excitation efficiency measurement method with bichromatic force. Theoretically, STIRAP can produce 100% population transfer, but it is typically far less efficient in practice. We will discuss the potential reasons for efficiency loss in three-level population transfer, especially the effect of velocity spread in atomic beam, and the solutions to overcome the efficiency loss.
