Ultrashort laser pulses have become an indispensable tool in physics, chemistry and engineering. Their numerous applications call for accurate and robust characterization techniques able to reliably retrieve the pulse’s intensity profile. Different methods, such as FROG  or SPIDER  and their variants, have been developed in past decades and are now common in many laboratories. More novel approaches based on manipulating the light’s spectral phase include techniques like MIIPS  and dispersion scan (d-scan) .
