Two-photon ablation with 1278nm laser radiation
... The use of femtosecond pulses and tight focusing leads to very high peak intensities, therefore allowing a precise two-photon interaction. It is crucial that the pulse duration of the radiation delivered to the sample is kept as short as possible. Here the low GVD of the Cr:Forsterite radiation in t ...

... instead of 75 fs, centered at the same wavelength, we should obtain 2.5 fold higher signal. However reduced pulse duration is associated with increased bandwidth of the laser, thus dealing with the dispersion by the optical elements becomes more difficult. For such a short pulses as 30 fs the higher ...
