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. 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 . inbox winghinWebThe temporal chirp of a light pulse is usually understood as the time dependence of its instantaneous frequency.

WebThe amount of chirp can be deter- mined as follows. Assuming that the pulse shape is Gaussian, the optical signal can be written as E( 0 ,t) = A 0 exp(−t 2 /T 02 ) exp[−i ω 0 ( 1 + δ sin ωmt)t], (7.2) where the carrier frequency ω 0 of the pulse is modulated sinusoidally at the frequency ωm with a modulation depth δ.
