Popis: A general formula is proposed for calculating the intensity of amplified spontaneous emission (ASE) in low, medium and high intensity regimes for both homogeneous and inhomogeneous line broadening. The calculation of ASE intensity is based on the results that are obtained from the numerical solution of the rate equations. The results compared with the corrected Linford formula in low intensities and asymptotic limiting formula for the high gain saturation. An error analysis over the entire region of the gain length product is also given to evaluate the validity of the proposed formula.
