…photodetector
array. The d-scan modules tailored for an HCF system comprises a chirped mirror compressor
including a pair of thin glass wedges on translation stages, providing both positive and negative
dispersion. After the pulses pass the compressor, a small portion undergoes…

…certain bandwidth and pulse
width produced by the laser, delivered
pulse width can be adjusted by introducing the appropriate level of chirp. In
some applications, those having a lot of
downstream optics, particularly transmissive components, such as acousto-optic
modulators…

…Figure 4.
Practical implementation of GDD precompensation
can be done with chirped mirrors [11] as long as the
wavelength being used is fixed and the amount or
variability of negative chirp is limited. However,
typical commercial, tunable Ti:S laser systems are now available…

wavelengths are delayed in one grating (normal dispersion for positive chirp) while long
wavelengths are delayed in the other (anomalous dispersion for negative chirp). By matching the
dispersion profile of the stretcher and compressor, the amplified pulse will…
