Quantum beat observations in rubidium vapor
… between a mode-locked laser pulse and saturated rubidium vapor with a pump–probe technique has resulted in observations of coherences within the atom that persist longer than 150 ps. Quantum beats due to the interference between the 7S and 5D_{5/2} energy states were observed by a four-wave …

Light Scattering in Ultracold High Density Rubidium Vapor
<p>Recent developments in laser cooling and trapping opened the door to a world full of new opportunities for research in atomic, molecular and optical physics as well as condensed matter physics. It became possible to do experiments under conditions that are hard to achieve in condensed matter …

Four-wave mixing with hermite-gauss modes in rubidium vapor
… wave diode laser to excite a sample of Rubidium atoms, on the ⁸⁵Rb D2 line, tuned to the frequency of the 5²S_(1/2) (𝐹 = 3) → 5²P_(3/2) transition. With a Spatial Light Modulator, we were able to split the laser beam in two and structure them in the desired modes. These two beams, A and …

Nonlinear optical processes and the nearest neighbor distribution in rubidium vapor
… four-wave mixing (PFWM), are studied in rubidium vapor. A theoretical framework is introduced that enables accurate calculations of nonlinear light-matter interactions, and calculations of these interactions using this framework are performed for a broad range of excitation conditions. In …

Study of Wavepacket Dynamics in Rubidium Vapor by Means of Time-Frequency Analysis
Wavepackets are excited in rubidium vapor by intense ultrashort (∼100 fs) pulses centered at a wavelength of 620 nm or 770 nm. The generated atomic wavepackets are optically detected via a pump-probe experiment based on axially phase-matched parametric four-wave mixing (FWM). This nonlinear …

Probing weakly bound long-range Rydberg molecules by quantum beating experiments in rubidium vapor
… Rydberg molecules (LRRM) associated with rubidium atomic states with low angular momentum and very low principal quantum numbers (7$s$, 8$s$, 5$d$, 6$d$) are observed in a quantum beating experiment for the first time. The experiments are conducted using parametric four-wave mixing (PFWM) …

On-Chip Atomic Spectroscopy
This thesis presents the integration of atomic vapor cells with anti-resonant reflecting optical waveguides (ARROWs) fabricated on silicon chips. These potentially provide a compact platform for a number of optical applications, including the study of quantum coherence effects such as …
