Gaussian temporal profile
WebApr 14, 2024 · The spot with the Bessel function profile is measured at 10.24 m without optical lenses, and the photonic chip’s operation wavelength can be continuously performed from 1500 to 1630 nm. In optics, a Gaussian beam is a beam of electromagnetic radiation with high monochromaticity whose amplitude envelope in the transverse plane is given by a Gaussian function; this also implies a Gaussian intensity (irradiance) profile. This fundamental (or TEM00) transverse Gaussian mode describes the intended output of most (but not all) lasers, as such a beam can be focused into the mo…

Web2 days ago · In the meanwhile, the temporal part is a combination of Gaussian time profile and time-harmonic factor. Hence, the incident field can be written in a general form E 0 t = E 0 e-α p t 2 e-i ω 0 t, with α p = 4 ln 2 / τ p 2 related to the duration of the pulse τ p and the central frequency ω 0. Hereinafter, we set E 0 = 1 V / m for simplicity.
