Abstract

We experimentally demonstrate the creation of two correlated beams generated by a nondegenerate four-wavemixing amplifier at λ = 795nm in hot rubidium vapor. We achieve intensity difference squeezing at frequencies as low as 1:5 kHz which is so far the lowest frequency to observe squeezing in an atomic system. The squeezing spans from 5.5 to 16:5MHz with a maximum squeezing of ?5 dB at 1 MHz. We can control the squeezing bandwidth by changing the pump power. Both low frequency and controllable bandwidth squeezing show great potential in sensitivity detection and precise control of the atom optics measurement.
