摘要：
Using optical phase-locking and a buffer gas, coherent population trapping resonances with linewidths below 50 Hz can be observed in a thermal cesium vapor. External influences on the cesium multilevel system, such as magnetic fields, laser polarizations and intensities, have been studied and can quantitatively be described by intuitive theoretical models. Based on these investigations we have performed precision measurements, for instance the sensitive detection of magnetic fields in the pT (ac) and nT (dc) range and the determination of g-factor ratios.
