Nonlinear optical processes and the nearest neighbor distribution in rubidium vapor
… optical processes, with a particular emphasis on parametric 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 …

Dynamics of interfering wave packets in rubidium by high resolution quantum beat spectroscopy
… spectroscopy has been realized to study atomic wave packet dynamics. Wave packets comprising pairs of low quantum number (n = 5 - 8) electronic states were formed in Rb vapor with ultrafast laser pulses, and their dynamics was observed by an all-optical technique of parametric four wave mixing …

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
… first time. The experiments are conducted using parametric four-wave mixing (PFWM) in a pump-probe fashion. Fourier analysis of the time-domain data yields a spectrum on which various quantum beats are identified. Energy spacings between adjacent vibrational levels within each LRRM's quantum well …

Έλεγχος της μίξης κυμάτων και της δημιουργίας αργού φωτός υπό συνθήκες ηλεκτρομαγνητικά επαγώμενης διαφάνειας και ενίσχυσης χωρίς αντιστροφή πληθυσμού σε μεταλλικούς ατμούς
… ακτινοβολιών από σύμφωνη παραμετρική μίξη (parametric four-wave mixing) ή και μερικώς σύμφωνο μηχανισμό όπως η ενισχυμένη αυθόρμητη εκπομπή (amplified spontaneous emission) ή υπέρ σκέδαση- Raman (stimulated hyper-Raman scattering), όταν το nsec πεδίο laser διεγείρει με δύο φωτόνια την …
