WebTo perform optical pumping of the Rb, the outputs of two distributed feedback laser diodes tuned near the Rb D1 transition (one on either side of resonance) are overlapped (see Figure 2). This is accomplished by polarizing pump A so that it is mostly transmitted by a polarizing beam splitter (PBS) and pump B so that it is mostly reflected by the same PBS. WebThe synchronous motor is a type of AC motor that runs at synchronous speed. The asynchronous motor is a type of AC motor that runs on speed less than the synchronous …
WebFor optical parametric oscillators (OPOs), synchronous pumping is the only option for generating ultrashort pulses, because a parametric device is not able to store the pump … Webratio alone. We suppress longitudinal polarization by optically pumping 85Rb atoms transverse to a pulsed bias eld [4]. The bias eld pulses are low duty cycle and produce 2ˇ precession of the Rb atoms. The noble gas nuclei 129Xe and 131Xe are simultaneously polarized via spin-exchange collisions with the Rb atoms.
