In this paper, the optical gain in multilayered quantum dot is calculated for typical GaAs/AlxGa1-xAS. For this purpose, by using numerical solution of the Schrödinger equation is obtained the energy levels and their corresponding wave functions of electrons and holes. Results are used to obtain the maximum optical gain of this nano structure. The effects of geometrical parameter and external parameter such as hydrostatic pressure, and temperature on the maximum optical gain are investigated. Numerical results clearly show that by increasing of width of the first well 68A• and decreasing the width of second well, temperature and pressure the optical gain increases.
