WebApr 12, 2024 · The pump fluence–dependent emission spectrum for the system is shown in fig. S13B. When the pump power was relatively low, a broad SE band centered at 526 nm with an FWHM of ~16.4 nm was obtained. At the threshold pump fluence (2.4 μJ/cm 2), a sharp peak with a compressed FWHM emerged. WebOne very common mistake when calculating spectral resolution is to overlook the fact that in order to determine the FWHM of a peak, a minimum of three pixels is required, therefore the spectral resolution (assuming the Ws = Wp) is equal to …
