Survival function of the ORL emission. Survival function S(I) pooled across wavelengths for pump fluences (a) 333.71 mJ/cm2, (b) 460.49 mJ/cm2, (c) 552.94 mJ/cm2, and (d) 774.16 mJ/cm2. Orange curve is obtained from the intensities pooled across wavelengths after normalizing by their corresponding shot-averaged value at each wavelength, while the blue curve is obtained from the intensities pooled across the wavelengths and shots before normalizing by their average value. A power-law line (green curve) with exponent −1 is shown for reference. (e,f) Sample emission spectrum and (g,h) lasing mode survival functions of the ORL at pump fluences: (e,g) 333.71 mJ/cm2 and (f,h) 552.94 mJ/cm2. Survival functions of the lasing modes show faster than the exponential decay due gain saturation in the ORL.
