Abstract

We experimentally demonstrate the creation of two correlated beams generated by a nondegenerate four-wave- mixing amplifier at λ=795nm in hot rubidium vapor. We achieve intensity difference squeezing at frequencies as low as 1.5kHz 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 5dB at 1MHz. 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.
