摘要：
An investigation of the laser radiation effects of a hydrogenic impurity in a quantum dot has been performed by using the matrix diagonalization method. We find that the laser field amplitude has an important influence on the linear, third-order nonlinear, and total absorption coefficients as well as the refractive index changes.
