Effect of GVD on short pulses with a broad bandwidth. The broader the bandwidth , the
more the pulse is stretched. Longer wavelengths travel faster through the glass than shorted
wavelengths in the pulse. Thus, a positively chirped pulse is broadened.
It is possible to compensate for GVD along the routing path and in the microscope to preserve the pulse
length to the sample by using a prechirp unit (available from other manufactureres).
