Linear and nonlinear magneto-optical absorption in a quantum well modulated by intense laser field

Abstract

The linear and nonlinear magneto-optical absorption via one and two-photon processes in a quantum well modulated by intense laser field have been studied numerically. The analytical expression of the magneto-optical absorption coefficient (MOAC) is obtained by relating it to the transition probability for the absorption of photons. The effects of the intense laser field, the magnetic field, and the temperature on MOAC and full-width at half-maximum (FWHM) of absorption peaks are investigated. Results reveal that MOAC and FWHM are the monotonic functions of magnetic field and temperature but are the non-monotonic functions of the laser dressing parameter in both one and two-photon absorption processes. Obtained results suggests useful way to control the magneto-optical properties of quantum well using the intense laser field.
