Chirped gaussian pulse
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 … 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 .

WebMar 3, 2012 · Recently, somewhat related idea of using chirped pulses in CARS spectroscopy has been demonstrated experimentally, 13 where the two equally chirped pulses were used. Time delay between pulses has been utilized as an effective way to tune two-photon detuning into resonance.

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].
