A chirped pulse is a short optical or electromagnetic pulse in which the frequency and phase change over time. The use of chirped laser pulses, where the laser frequency is dynamically varied during the pulse duration, has been shown to enhance optical forces significantly, leading to applications in quantum control, laser cooling, and atomic state preparation. In this presentation, we will talk about how radio-frequency driven Acousto-Optic Modulator (AOM) generates controlled frequency sweeps (chirped) optical pulses. The chirped laser pulse will be used to sweep the frequency of the laser across resonance slowly enough to maintain adiabatic evolution. Then, the system is robustly transferred from ground state to excited state if frequency sweeps (chirp) is slow compared to the Rabi frequency. By sweeping the laser frequency dynamically, we aim to achieve robust and efficient population transfer in atoms and molecules.
