Abstract
The elementary excitations energetic spectrum of the system of biexcit ons in the presence of Bose-condensed quasiparticles induced by the la ser radiation due to two-photon transitions was investigated. It was s hown, that in some regions of wave vectors the instabilities in the en ergetic spectrum can appear. They depend essentially on the laser freq uency detuning and light intensity. The same result is true for the sy stem of excitons in the presence of resonant laser radiation which ind uces the corresponding Bose condensed state due to one-photon transiti ons.
