Phase-sensitive Manipulations of Squeezed Vacuum Field in an Optical Parametric Amplifier inside an Optical Cavity
Jing Zhang, Chenguang Ye, Feng Gao +1
Squeezed vacuum field can be amplified or deamplified when it is injected, as the signal beam, into a phase-sensitive optical parametric amplifier (OPA) inside an optical cavity. T…
Observation of lasing without inversion in a hot rubidium vapor under electromagnetically-induced transparency conditions
Haibin Wu, Min Xiao, J. Gea-Banacloche
We have observed CW lasing without inversion in a gas of hot rubidium atoms in an optical cavity under conditions of electromagnetically-induced transparency (EIT). The medium is p…
Preparation and Determination of Spin-Polarized States in Multi-Zeeman-sublevel Atoms
Bo Wang, Yanxu Han, Jintao Xiao +5
We demonstrate a simple technique to prepare and determine the desired internal quantum states in multi-Zeeman-sublevel atoms. By choosing appropriate coupling and pumping laser be…
Controlled polarization rotation of an optical field in multi-Zeeman-sublevel atoms
Shujing Li, Bo Wang, Xudong Yang +4
We investigate, both theoretically and experimentally, the phenomenon of polarization rotation of a weak, linearly-polarized optical (probe) field in an atomic system with multiple…
Multi-dark-state resonances in cold multi-Zeeman-sublevel atoms
Bo Wang, Yanxu Han, Jintao Xiao +4
We present our experimental and theoretical studies of multi-dark-state resonances (MDSRs) generated in a unique cold rubidium atomic system with only one coupling laser beam. Such…
