Axial elongation of the PSF may also result from the pulse tilt acquired after their passing through prisms and gratings, for example, in pulse compressors used in the standard chirped pidse ampHfication (CPA) scheme [41]. The influence of spherical aberrations on the PSF is discussed in Sect. 3.1.2. 

Fig. 7.11. Four excitation-pulse waveforms achieving the highest ion yield ratio of ni29/m3i. Waveforms in a and b were obtained by the self-learning adaptive pulse control. The waveform in c was obtained by applying a linear frequency chirp at 2.2 x 10 2 ps2 by the 4/-pulse shaper. The waveform in d was obtained by applying a linear frequency chirp at 2.2 x 10 2 ps2 by adjusting the pulse compressor...

Experiments were performed using a visible optical parametric amplifier based on noncollinear phase-matching in /3-barium borate, followed by a pulse compressor using chirped dielectric mirrors. This optical source provides ultrabroadband pulses, with bandwidth extending from 500 to 720 nm, compressed to an almost transform-limited duration of 5-6 fs. The pump-...

The amplifier system is composed of three logic subunits, a femtosecond pulse stretcher (Fig. 2.27), the titanium sapphire regenerative amplifier (Fig. 2.28) and a femtosecond pulse compressor (Fig. 2.29). To exploit the storage capability of titanium sapphire the system uses chirped-pulse amplification [264-266]. For this a seed pulse (80 fs, 5nJ) of the titanium sapphire oscillator is stretched to about 500 ps and then amplified. The stretched pulse can be safely amplified because the peak power has been significantly lowered, thereby avoiding any nonlinear effects that could result in damage to the... 

Fig. 2.29. Top view of the femtosecond pulse compressor (Quantronix model 4822) and laser beam tracing. The compressor is built up in the same housing as the stretcher and the laser pulses run a similar way back, using the optical components of the pulse stretcher, especially the diffractive grating. By means of the Faraday rotator (FR) the polarization of the light pulses is timned 90° (45° for each through run) and hence, at the latter thin-film polarizer (TFP) the pulses are now reflected. A aperture (by courtesy of Quantronix)...
