Chirped gaussian pulse
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. 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

Source publication Interaction of strongly chirped pulses with two-level atoms Article Full-text … WebSep 12, 2024 · When a chirped Gaussian pulse crosses a temporal boundary, the shape of the reflected spectra is distorted by adjusting chirp parameters. However, the transmitted spectra retain the Gaussian shape. The shape of the final output spectra is the same if the absolute values of the chirp are the same.
Weba Gaussian pulse, the FWHM duration DT (intensity) of the chirped pulse is DT DT 0 Ω 1 1 24 ln 2F v 0 2 DT 0 4 æ 1 2, (2) where DT 0 is the Fourier-limited duration of the pulse. By combining the time–bandwidth product and the linear chirp, we obtain a value of the minimum per-turbation duration dt for which the linear chirp band- A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal. It is commonly applied to sonar, radar, and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum). This signal type is biologically inspired and occurs as a ph…
Webb) Sketch the chirped Gaussian pulse caused by SPM and explain the chirping properties based on results of part a. c) A soliton pulse is created when the dispersion of the medium produces an opposite chirp relative to the chirp produced by SPM.
