The characteristic features of the stimulated Raman backscattering of short modulated (multifrequency) laser pulses in an underdense plasma are investigated. A laser pulse consisting of a given pair of spectral components with the frequency difference close to the double plasma frequency is studied in the weak mode coupling approximation. The scattering of the component with the higher frequency is shown to be a fivewave resonant process, and the conditions under which this process is totally suppressed are found. The scattering of the component with the lower frequency is an ordinary threewave decay process without any suppression. When the difference between ...

Squeezing the quantum fluctuations of the twomode light due to the nonstationary coupling between the quadrature components q_1 and q_2 is examined. The deltafunction and stepfunction mode couplings are considered. The conditions of weak and strong stepfunction coupling are distinguished, the latter being the condition of the instability for the classical counterpart of the quantum system under study. Under the conditions of weak coupling the quadrature squeezing is established in both a twomode electromagnetic noise in thermal equilibrium (the thermal state) and a two mode correlated coherent state (CCS). Squeezing in the thermal state is suppressed at a high temperature ...
