WebApr 10, 2024 · The temporal profile of the laser pulse is Gaussian with a duration of 1 ps (full width at half maximum, FWHM). The fast electrons are injected from the left boundary (x = 0) and are assumed to have an exponential energy distribution f(E) = (1/ E )exp(−E/ E ), where E is the average energy given by the ponderomotive scaling, 32 32. S. WebFor c = 2 the constant before the standard deviation in the frequency domain in the last equation equals approximately 1.1774, which is half the Full Width at Half Maximum (FWHM) (see Gaussian function). For c = √ 2 this constant equals approximately 0.8326. These values are quite close to 1.
WebOct 1, 1996 · The effect of approximating a continuous Gaussian distribution with histogrammed data are studied. The expressions for theoretical uncertainties in centroid and full-width at half maximum (FWHM), as determined by calculation of moments, are derived using the error propagation method for a histogrammed Gaussian distribution. WebOct 19, 2024 · I need to calculate the spectral full width at half max (FWHM) of a Gaussian light pulse. The frequency spectrum of a Gaussian light pulse is $$ \tilde{E}(\omega)\propto \exp{-\frac{(\omega-\omega_0)^2}{4\Gamma}}$$ with the complex Gauss parameter $\Gamma=\Gamma_1-i\Gamma_2$ from the Gaussian pulse
WebJun 15, 2015 · Generally speaking there are two ways of doing that: 1) fit with predefined function (good candidates at mathworld.wolfram.com/FullWidthatHalfMaximum.html) and then use FWHM calculated from fitted parameters - this is what @ubpdqn did or 2) if you have no idea about the function, you can cutoff all points outside of your peak and …
