The previous theoretical study has shown that pulse irradiation to the Mottinsulating state in the Hubbard model can induce the enhancement ofsuperconducting correlation due to the generation of $\eta$ pairs. Here, weshow that the same mechanism can be applied to the Kondo lattice model, aneffective model for heavy electron systems, by demonstrating that the pulseirradiation indeed enhances the $\eta$-pairing correlation. As in the case ofthe Hubbard model, the non-linear optical process is essential to increase thenumber of photoinduced $\eta$ pairs and thus the enhancement of thesuperconducting correlation. We also find the diffusive behavior of the spindynamics after the pulse irradiation, suggesting that the increase of thenumber of $\eta$ pairs leads to the decoupling between the conduction band andthe localized spins in the Kondo lattice model, which is inseparably related tothe photodoping effect.
