Extreme pulse-front tilt from an etalon
... [15]. By the above Fourier-transform result, the huge angular dispersion of etalons implies that their output pulse front must be very tilted—by as much as 100 times that due to a diffraction grating. Indeed, that can be seen by simple light-travel-time considerations: the part of the pulse that mak ...
