| Plots of the calculated ASE intensity versus normalized frequency offset x = 2( ν − ν 0)/Δ ν 0 (a) for z = 0.203 cm, showing that the calculated intensity favors a Gaussian distribution and verifies the x 2 ≪ 1 approximation for the intensity; (b) for z = 0.013 cm, showing that the calculated intensity has a Lorentzian distribution and that corresponds to the x 2 ≫ 1 approximation. Both panels (a) and (b) correspond to I p = 4.1 kW/cm2; (c) the plots of normalized ASE intensity versus wavelength for I p = 5.2 kW/cm2 measurements as given in Ref. [ 6 ]. The experimental measurements show that I ASE at high pump intensity, when z ≫ z sat is satisfied, favors a Gaussian frequency distribution. |
