In this paper, we have studied the effect of intense laser field on excitonic states of excitons confined in spherical quantum dots by means of variational technique within the effective mass approximation. The results show that the exciton binding energy depends on the laser field parameter and quantum dot radii. And the laser field lowers total energy (E), kinetic energy (T) , coulombic potential (Vc) and the binding energy of exciton for all confinements and for any material used.
