Cím: Introduction to spatio-temporal couplings of ultrashort lasers: 
metrology and applications

Az előadássorozat kivonata:

The accurate temporal characterization of ultrashort laser pulses has now 
become a routine procedure in all labs working with femtosecond lasers, 
providing the complex field E(t) of these pulses, and such measurements have 
become a key tool for the optimization and control of laser-matter 
interaction experiments. Yet, they are actually insufficient to fully 
characterize an ultrashort laser beam, which is intrinsically a 3D physical 
object, described by a  complex field E(x,y,t), where x and y are the spatial 
coordinates transverse to the propagation direction. In many cases of 
interest, the spatial and temporal dependences of this field cannot be 
separated: in such instances the beam is said to exhibit spatio-temporal 
couplings (STC). Thanks to the work carried out by a few groups in the last 
decade, measurement techniques and devices are now available to fully 
determine the field E(x,y,t) in such cases. Furthermore, there are now 
several striking examples of how to take benefit of carefully controlled STC 
to finely control laser-matter interaction processes, especially at ultrahigh 
laser intensities and down to the attosecond time scale. This series of 
tutorial will provide an accessible introduction to STC, their metrology and 
a few selected examples of their applications.
