A Booklet for Properties of Optical Materials

Probably most of you know that many companies have small booklets regarding different topics/ technologies on their webpages. One which I personally like is from the Oriel-LOT company and summarizes the properties of optical materials, especially transmission curves. Unfortunately it is only available in german but this will not limit you as the booklet contains to 95% transmission curves and datas, understandable for everyone.

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.

(from attoworld)


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

Please download (free, no registration) Attogram from following page:


There you can find the system requirements too. Don't hesitate to contact the programmer if you have any questions or comments (contact on the download page).
