Look how nightingales sang of old, cocks crowed, kine lowed, sheep bleated, sparrows chirped, dogs barked, so they do still: we keep our madness still, play the fool still; we are of the same humours and inclinations as our predecessors were; you shall find us all alike, much as one, we and our sons, and so shall our posterity continue to the last. Some other techniques can be used for stretching and compressing pulses, but these are not suitable as the main stretcher/compressor in CPA due to their limited amount of dispersion and due to their inability to handle high-intensity pulses. Then the stretched pulse, whose intensity is sufficiently low compared with the intensity limit of gigawatts per square centimeter, is safely introduced to the gain medium and amplified by a factor of a million or more. 2, which introduces additional dispersion. ω The dispersion can be tuned easily by changing the distance between the two gratings. CPA is the current state-of-the-art technique used by most of the highest-power lasers in the world. case is used in Femtosecond pulse shaping. τ Prisms and gratings are sometimes combined to correct higher order dispersion ("grisms"), in which case the distance between the prisms is on the order of 10 meters rather than 50 cm as with a grating compressor. chirp definition: 1. 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. N Usually, the focusing element is a spherical or cylindrical mirror rather than a lens. This setup is normally used as a compressor, since it does not involve transmissive components that could lead to unwanted side-effects when dealing with high-intensity pulses. (of a person) say something in a lively and cheerful way. With lenses, the sign of the dispersion can be reversed, similar to Figure 2. τ In a CPA, the dispersions of the stretcher and compressor must cancel out. Petrarch observes, that we change language, habits, laws, customs, manners, but not vices, not diseases, not the symptoms of folly and madness?they are still the same. The stretching and compression uses devices that ensure that the different color components of the pulse travel different distances. = Gratings lose power into the other orders while prisms lose power due to Rayleigh scattering. 1(of a small bird or an insect) make a short, sharp, high-pitched sound. {\displaystyle \tau (\omega )} ) For this reason, it is normally used as a stretcher before the amplification stage, since the low-intensity seed pulses can be collimated to a beam with a small diameter. {\displaystyle \lambda } N {\displaystyle L} For example, some of the most powerful compressed CPA laser beams, even in an unfocused large aperture (after exiting the compression grating) can exceed intensities of 700 GW/cm2, which if allowed to propagate in air or the laser gain medium would instantly self-focus and form a plasma or cause filament propagation, both of which would ruin the original beam's desirable qualities and could even cause back-reflection potentially damaging the laser's components.
