Squeezing is an effect which characterizes a field state in which the variance of one of two non-commuting observables is less than one-half of the absolute values of their commutator. Squeezing is observed in a certain number of quantum – mechanical systems such as parametric oscillators, free – electron lasers, resonance fluorescence processes etc. Here, we discuss squeezing effects in resonance fluorescence processes occurring in a pumped molecular system possessing permanent dipoles. Particularly, we present the solution of the basic master equation derived in the high – field limit approximation. The analytical expressions for the coherent operators and spontaneous emission rates defined in “double dressed” state basis are used to compute the spectrum of squeezing. Finally, we analyze the behavior of photon squeezing spectrum.
