If you work with homebuild lasers then this video looks quite crazy... It shows a shaking test with a femtosecond laser.
The video was made by Femtolasers Produktions GmbH with one of their turn key laser-systems (Integral).
There is even a more impressive video by Toptica, where they have left falling a laser onto the floor (if i remember correctly) but unfortunately I havent found it yet on the internet nor their homepage. If you have it, please post it!

Attosecond laser - the world's fastest laser
By chance I found this video over an attosecond laser at the Max-Planck-Institute of Quantum Optics (MPQ) in the group of Prof. Dr. Ferenc Krausz (www.attoworld.de). The video is on public level and nice to watch.
Additional information you can find in the press release (click) or at Attoworld.
Enjoy!
btw... did you found the mistake in the video? Everyone has once a bad day ;)

IONS-9 in Salamanca!
Don't miss it! Present and discuss your research with other young scientists.
IONS stands for International OSA Networks of Students and has the aim to connect you with young researchers in optics and photonics. Therefore there is no special conference topic but you can present your results and research to young scientists. Discuss, and get informed about the projects of other young scientists. More about the IONS, what they do and where the next IONS will be held you can find out here.
The next IONS in europe will be held in Salamanca, Spain, from the 7. - 9. April 2011 and is organized by the OSAL student chapter. Registration is free and open until the 25. february. For travel grants one can apply until the 7. february. Please check the IONS-9 Salamanca homepage for more information and details, or the IONS-facebook page. The poster can be downloaded here (2MB).
Check the IONS page and register today!

Optics & Photonics Focus
It is time to know this page, in case you have overlooked it like me.
It is a magazine (sponsored by EPS and OSA) presenting recent interesting and important developments in the fields of optics and photonics. The topic selection over the last years is well done and you will find many interesting articles respecively reviews. They have a nice length to read and are not too specific written, accessible for a wide range of readers. Have a look at the archive

OPFocus Archive
All articles are online available. Take time for an overview, and perhaps you even have a suggestion for them what to present next!

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.
You can download the booklet (pdf) here:

If you know other booklets which helped you in your work, feel free to post a comment!

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).

Big Laser Assembling...
In May 2008, the assembling of one of the largest laser systems in the world, hosted at the Laboratory for Laser Energetics at University of Rochester, was after 3 years completed. This laser system is used for the same objects like at NIF (see post), namely for inertial confinement fusion. The following time lapse movie of the laser construction gives you a nice idea about its dimension. The main view is on this hall, which contains the "OMEGA EP" laser system.
Have fun watching it!
More time lapses movie can be found here.
