Since 1992, APE is passionately supporting customers to get the best out of their ultrashortpulse (USP) & ultrafast lasers, applications, and processes. To calculate Pulse Energy, enter the Pulse Power and Pulse Duration, then click Compute. The first calculator computes the transform-limited, i.e. For other shape pulses, the result will not be completely accurate. Angular frequency $$\omega = \frac{2\pi c}{\lambda} \Longrightarrow \omega[\mathrm{fs^{-1}}] \approx \frac{1883.652}{\lambda[\mathrm{nm}]} $$ From the above equation, the pulse width for a 1 GHz Clock is 0.5 nanoseconds. Here \( \vartheta_0 \) is the angle of incidence. There is a frequency component to shocks also. $$, Peak width relations: $$ \mathrm{FWHM} = 2\sqrt{2\ln2}\sigma,$$ $$D_{1/\mathrm{e}^2} = 4\sigma = \sqrt{\frac{2}{\ln2}}\mathrm{FWHM},$$ $$D_{1/\mathrm{e}} = 2\sqrt{2}\sigma = \frac{\mathrm{FWHM}}{\sqrt{\ln 2}}.$$, Exact and approximate relations between the bandwidth in wavenumber and wavelength units is given by: $$ \Delta k = \frac{\Delta\lambda}{\lambda_0^2 - \frac{\Delta\lambda^2}{4}} \approx \frac{\Delta\lambda}{\lambda_0^2} .$$ Next, the expected autocorrelation widths are calculated by dividing the supplied pulse duration by the deconvolution factors for Gaussian and sech² pulses. $$, Carrier-envelope phase \( \varphi_\mathsf{CE} \) is the phase difference between the maxima of (i) oscillating field intensity and (ii) carrier envelope.
