ABSTRACT

A phase response of dye solution and saturation processes can be taken into consideration to describe a nonlinear medium. Nonlinear medium can be modeled by a typical three-level configuration (S0-S1-S2), for which the transition of molecules in principal channel (S0-S1) are occurred by the light fields of intensity I12 at frequency ω0. At the same time, light fields with intensity I23 at frequency ω interact with excited molecules to form their transitions in excited channel (S1-S2). The phase response of dye solution in principal channel (S0-S1) reaches saturation at intensity . At this point, the saturation intensity decreases with increasing radiation intensity in the excited channel I23. The saturation intensity has its optimum (minimum) values when the frequency of light fields in principal channel is tuned into the centre of principal absorption band. In addition, the saturation intensity has its optimum value when the radiations in excited channel have enough high intensity I23 and a frequency tuning into the centre of absorption excited band.
