    "abstract": "Quantum theory of self-phase and cross-phase modulation of ultrashort light\npulses in the Kerr medium is developed with taking into account the response\ntime of an electronic nonlinearity. The correspondent algebra of time-dependent\nBose-operators is elaborated. It is established that the spectral region of the\npulse, where the quadrature fluctuations level is lower than the shot-noise\none, depends on the value of the nonlinear phase shift, the intensity of\nanother pulse, and the relaxation time of the nonlinearity. It is shown that\nthe frequency of the pulse spectrum at which the suppression of fluctuations is\nmaximum can be controlled by adjusting the other pulse intensity.",
