Attogram - free software

This post addresses more the specialists working with attosecond pulses. If you want to learn more about attosecond optics and its techniques, please read following article "attosecond physics" or visit "attoworld".

Measuring the pulse duration of an attosecond pulse is not so easy as you do with a 20fs pulse. To do so, you have to perform a streaking measurement from which you can reconstruct the desired data. Attogram is a programm designed "to reconstruct the temporal profiles of an attosecond pulse and a laser field from a streaking measurement". It also enables to analyze the chirp of the attosecond pulse.

Attogram is based on a blind FROG algorithm, and can also perform PG, SHG, THG and SD FROG retrievals. More detailed informations about the algorithm and its operation can be found in Applied Physics B 92, 25-32 and for the programm in the manual
