High-resolution interferometric diagnostics for ultrashort pulses

Thesis

I present several new methods for the characterisation of ultrashort pulses using interferometry.

A generalisation of the concatenation algorithm for spectral shearing interferometry enables interferograms taken at multiple shears to be combined. This improves the precision of the reconstructed phase in the presence of detector noise, and enables the relative phase between disjoint spectral components to be obtained without decreasing the spectral resolution. The algorithm is applied...
