We present three additional theoretical signatures of quantum jumps displayed by the behavior of the Mandel Q(T) function, transient squeezing, and the time-dependent spectra, for a Raman system resonantly driven by coherent fields. As in our earlier formalism we assume that one or both of the driving fields are intense and invoke the secular approximation to derive a Markovian master equation for the atomic-density operator. This is then used to obtain analytical expressions for Q(T), transient squeezing parameters, and the time-dependent spectra. These analytical results provide further characteristics of the quantum jumps.
