Sažetak
Gain and loss parameters of (AlGa) As-GaAs single heterostructure laser have been determined by changing the reflectivity of one facet of the laser with ZnS optical films evaporated in controlled steps. The measurements gave a linear dependence of gain on threshold current density. The results so obtained on the lasing photon energy and threshold current density were in agreement with the previously reported theoretical models derived on the assumption of high concentration of impurity band tail states.
