Chirped gaussian pulse
WebWe frequency doubled an externally chirped erbium-doped fiber laser generating 17-ps (FWHM) pulses at 1560 nm to produce near-transform-limited 110-fs (FWHM) pulses at 780 nm by use of a... WebThis definition arises naturally from the mathematical fact that the Fourier transform of a Gaussian-windowed chirp signal is a complex Gaussian pulse, where a chirp signal is defined as a sinusoid having linearly modulated frequency, i.e., quadratic phase: (11.25) Applying a Gaussian window to this chirp yields (11.26) where .

WebGiven a Gaussian pulse with central wavelength 550 nm and a HMFW of 300 nm, and let's assume the pulse is transform-limited. I need to get the pulse through 1mm of quartz. I expect group delay dispersion (second order dispersion) to spread in time the wavelengths from each other making the red end arrive sooner then the green then the blue end.
WebA linearly chirped Gaussian pulse in a disper-sive medium is completely characterized by the position and (minimum) duration of the unchirped pulse, just as a spatially Gaussian … oracle and biWebThe pulse is chirped. Chirp refers to a signal in which the frequency increases or decreases with time.
