摘要：

The quantum limit for the resolution of a small force using an optical transducer of a displacement with a coherent nonmodulated pump is proved to be less than the standard quantum limit if one measures the quadrature amplitude in the output wave, squeezed by the ponderomotive nonlinearity mechanism. This squeezing has a spectral dependence and we propose a procedure showing it.
