Pulsed pump in optical displacement transducer for experiments with probe bodies
Abstract
The sensitivity of the displacement transducer pumped with a train of high-intensity laser pulses is estimated. Due to the multicomponent character of the pump a consideration of transformations of the signal and the noises between optical modes plays an important role in estimation of the potential sensitivity. An expression for the minimal detectable external classical force resembles those for the continuous wave pumping with substitution of the laser power by a time averaged power of pulsed laser. Possible scheme for back action noise compensation for such transducers is considered. For full suppression of back action noise the field of local oscillator has to be pulsed with the same time dependence as the pump field.
