Abstract
The quantum limit for the resolution of a small force using an optical transducer of a displacement with a coherent nonmodulated pump is pro ved to be less than the standard quantum limit if one measures the qua drature amplitude in the output wave, squeezed by the ponderomotive no nlinearity mechanism. This squeezing has a spectral dependence and we propose a procedure showing it.
