Webposition, that is, introducing spatial chirp, at its fo-cal plane (Fig. 1(c)). The accuracy of pulse shaping depends on the degree of spatial chirp at the focal plane, on which extensive studies have been carried out [2,4,5]. Other applications of spatial chirp in-clude the suppression of longitudinal mode compe-tition [6,7] in the laser design. WebTo demonstrate this, we use a chirped Gaussian pulse with the chirp parameter C = 2 (since β 2 < 0 in our case) (Figure 6). Figure 6: Setting the chirp parameter to observe …

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. WebPropagation of the pulse manipulates it. Dispersive pulse broadening is unavoidable. If 2 is the pulse 2nd-order spectral phase on entering a medium, and k”L is the 2nd-order spectral phase of the medium, then the resulting pulse 2nd-order phase will be the sum: 2 + k”L. A linearly chirped input pulse has 2nd-order phase: 2, 22 /2 in Webchirped. For d2ϕ/dt2 < (>)0 ...

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.

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.
