Pulse Shaping

On a fs time scale, many interactions depend on the particular temporal

shape of the waveform being applied. For many applications it is desirable and

necessary to modify the pulses from the source in a well-defined manner. A com-

pression of the intensity profile leads to shorter pulses and higher peak powers.

Closely spaced femtosecond pulses with controllable phase relations are needed

for coherent multiphoton excitation and the selective excitation of, for example,

certain molecular vibrations as detailed in Chapter 4.

The distortion of the complex pulse envelope caused by most linear and

nonlinear optical processes was discussed in ...
