Abstract :
It has been demonstrated that after 3 - 5 minutes irradiation of the MBE grown ZnSe-based electron beam pumped laser heterostructures with the light intensity of mercury lamp of 40-60 W/cm2, the luminescence intensity increased by ~20-50 %, whereas the threshold current density reduced by 20-40 %. Evidently, the results could be explained by the annealing (or optical transformation) the initial point defects in the active area of the laser heterostructure induced by low-temperature growth.
