In this paper, we studied theoretically the quantum beat of excitons in GaAs/AlGaAs quantum wells using renormalized wavefunction formulation of a three-level energy diagram. We observed the quantum beat of excitons while there was being a strong laser coupling two electron quantized levels. Quantum beat is observed at twice the electron Rabi frequency. In addition, we found dependences of intensity of absorption of the quantum beat of excitons on wells length and pump field detuning.
