Abstract:
Multiphoton Intrapulse Interference Phase Scan (MIIPS) is a pulse shaper based method
for laser pulse characterization in which the dependency of nonlinear optical processes on
the spectral phase of these pulses is exploited. By introducing a known reference phase
using a pulse shaper, this phase can be reconstructed iteratively by analyzing characteristic
features in second-harmonic spectra.
In the framework of this thesis, the underlying processes of MIIPS were simulated using
LabVIEW, an experiment was set up and a set of measurements was performed. Overall, a
good qualitative agreement between simulated and measured results as well as the general
functioning of MIIPS could be observed. Furthermore, the quality of phase reconstruction,
the impact of the laser beam profile and the used reference phase, among others, have
been investigated. Experimental results are well reproducible to an uncertainty of less
than 0.1 rad and exhibit good qualitative agreement with the expectation.
