用于探针体实验的光位移传感器中的脉冲泵浦

Pulsed pump in optical displacement transducer for experiments with probe bodies

Victor V. Kulagin

摘要:

估算了用高强度激光脉冲训练泵浦的位移传感器的灵敏度。由于泵浦的多分量特性,考虑光模之间的信号和噪声的变换在估计潜在的灵敏度中起着重要的作用。用脉冲激光的时间平均功率代替激光功率,得到了与连续波泵浦类似的最小可检测经典外力的表达式。考虑了这种换能器的反作用噪声补偿的可能方案。为了完全抑制反作用噪声,本机振荡器的场必须以与泵浦场相同的时间依赖性来脉动。

英文摘要:

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.
