WebFeb 26, 2024 · I would like to generate figure showing the a chirp pulse with the Gaussian envelope ( in the code) and to obtain its phase. I have execute the below code but it does not work. Because if it is correct, the spectrum should have the same shape as shown in the attached figure. So does anyone have any idea on that? This is the code I use: Theme … WebFinally, the calculator computes the chirp parameter C C and the accumulated group delay dispersion (assuming a Gaussian shape). The chirp parameter is C = \sqrt {\dfrac {T^2} {T_ {min}^2} - 1} C = T min2T 2 − 1 where T T is the 1/e 1/e pulse duration: T = \dfrac {\Delta\tau} {2\sqrt {\log2}} T = 2 log2Δτ
Webtc = gauspuls ('cutoff',fc,bw,bwr,tpe) returns the cutoff time tc at which the trailing pulse envelope falls below tpe dB with respect to the peak envelope amplitude.

My question is: what does the i signify here?
Chirped pulse amplification (CPA) is a technique for amplifying an ultrashort laser pulse up to the petawatt level, with the laser pulse being stretched out temporally and spectrally, then amplified, and then compressed again. The stretching and compression uses devices that ensure that the different color components of the pulse travel different distances.
