Spatiotemporal compression of ultrashort pulses is one of the key issues of
chirped pulse amplification (CPA), the most common method to achieve high
intensity laser beams. Successful shaping of the temporal envelope and
recombination of the spectral components of the broadband pulses need careful
alignment of the stretcher-compressor stages. Several diagnostic techniques
have been developed so far for the characterization of ultrashort pulses. Some
of these methods utilize nonlinear optical processes, while others based on
purely linear optics, in most cases, combined with spectrally resolving
device.
In this seminar I provide a review on the capabilities and limitations of the
latter category of the ultrafast diagnostic methods. I give a general
description on the background of spectrally resolved linear interferometry and
demonstrate various schematic experimental layouts for the detection of
material dispersion, angular dispersion and carrier-envelope phase drift.
Precision estimations and discussion of potential applications are also
provided.
