In this paper, we studied theoretically quantum beat of excitons in GaAs/AlGaAs spherical quantum dots using renormalized wavefunction formulation. We observed the quantum beat when there is a strong laser coupling two electron quantized levels. Quantum beat is observed at twice the electron Rabi frequency. In addition, we found the dependences of quantum beat absorption on dot radius and pump field detuning.
