摘要
We report on the generation of pulses of a low-frequency squeezed vacuum with noise suppression %26gt; 2 dB below the standard quantum limit in a hot resonant Rb-87 vapour with polarization self-rotation. We demonstrate the possibility of precisely controlling the temporal profile of the squeezed noise quadrature by applying a calibrated longitudinal magnetic field, without degrading the maximum amount of squeezing.
