Laserfest



16. May 1960: Theodore Maiman achieves for the first time in history light from a laser.
Thus,2010 is the 50th Anniversary of the first laser.
For this reason, there is an innitiative from APS, OSA, SPIE and IEEE to conmemorate this anniversary: Laserfest.

Events around the world will showcase how the laser works, the history of the laser and its impact on society, and the laser's potential for the future.

I strongly recommend you to visit the website for Laserfest.

Here you can find a lot of information and latest news about lasers, curiosities and of course, info about all the events related to Laserfest that will take place this year.

ELI - Extreme Light Infrastructure

The Extreme Light Infrastructure, called ELI, is a european project which will provide in ~ 2015 a new infrastructure for an ultra-high intensity laser to investigate laser-matter interactions in the unexplored ultra-relativistic regime.

From 13 european countries, more than 50 institutes are involved and cooperating for this project. The preparatory phase will end in November 2010, followed by a construction period of 5 years. The project will have 4 facilities located in Hungary, Czech Republic and Romania. The last location will be decided in 2012. The research focuses onto three fields:


  1. Ultra high science field (exploring laser-matter interaction)

  2. Attosecond laser science (temporal investigation of electron dynamics)

  3. High Energy Beam Science (development of ultra-short pulses of high energy radiation and particles (100 GeV) for fundamental and applied sciences)
But ELI is not only relevant for scientists. Public will benefit too of ELI as new techniques in medicine will be developed like new radiography and hadron theraphy methods. A big field will be also the laser driven nuclear physics which can help to find new ways to treat nuclear waste.
ELI will be a unique laser facility on the world, opening new ways to the secrets of matter on the ultra-short timescale. Although, 2015 seems to be far away, if you start now with your phd or study, you will be finished around the time when ELI will show its "first light", a perfect time or ;)?

Light for the Future!

A short but professional made video about the “Excellence Cluster MAP” in Germany. MAP stands for Munich Centre for Advanced Photonics and is sponsored/ granted by the “Deutsche Forschungsgemeinschaft DFG” (German Research Foundation). The first part of the movie shows laser and laserlabs whereas the second parts concentrates on possible applications in medecine. Have a look!



I couldnt implement the video directly into the blog, sorry. Additional information you will find on the same page too. Furthermore, more movies you can watch using the DFG Video Portal. Every monday a new research video will be published there.

"Brave New Attoworld"

Since beginning of the new year, the newly designed HOMEPAGE OF THE ATTOSECOND GROUP at the Max Planck Institute of Quantum Optics is online:



or: www.attoworld.de (startpage):

Attoworld contains a lot of interesting background information not only what we are doing, but also our techniques, aims, visions, challenges, information for public, even teaching etc... The attoworld section (attoworld) gives you a well understanding of what attoscience is. Take time to surf and to enjoy it. The homepage is very well linked too further information and gives access to many papers (free download).

As people often want to have a look into the laboratories, attoworld presents an extensive gallery of our works: Gallery Labs. But also you will find pictures everywhere at attoworld.


(Both pictures are from the gallery of attoworld. You can find there a detailed caption too.)

Enjoy... and dont forget the breakthroughs of the year vote!

The Breakthroughs of the year

2009 is coming to its end... and it is time to review the most important scientific contributions of the year.
For this reason the magazine Science has published a special issue with the top 10 breakthroughs of the year (according to Science). And the winners are...

1.- Ardipithecus ramidus. Ardi was an Ethiopian woman, 1.20 m tall... and who lived 4,4 million years ago! It is the most ancient hominid fossil ever found.
2.- Pulsars. Gamma rays Fermi NASA telescope has allowed to detect pulsars. The telescope was put in orbit in 2008, and providing a measurement that was a proof of the relativity theory has been its most important success so far.
3.- ABA receptors. Major advances in the knowledge of the structure of the drought hormone have been achieved during 2009.
4.- Monopoles. Two research group have achieved magnetic pertubations of monopoles from spin ices.
5.- Rapamycin. Rapamycin (a medicine used to prevent transplant rejection) can prolong mammal's life. The experiment was carried out in rats, that prolong their lives between 9% and 14%.
6.- Water in the moon. NASA announced on the 13th November that the Lcross spacecraft sensors had detected water vapour and ice in the moon.
7.- Genetic therapy. Advances in genetic therapy to treat blindness.
8.- Graphene. Latest research about the graphene properties has revealed that this material could replace silicon in chips.
9.- Hubble repair. Hubble repair mission prolonged its life and improved some features.
10.- X-ray laser. Since we reported in a post some months ago, SLAC laboratory started running the first X-ray laser.

And what is the most important discovery for you? Fill in the survey you can find on your right!

Also, you can also find a really interesting and comprehensive podcast about the 10 most popular stories of Science in 2009 (the transcript can be downloaded here).

PHD Comics: Laser in Use!

Dont worry. There are real lasers in our optic labs ;).
(click on the picture to enlarge it)

If you want to know how graduate students are living or how life in the lab really is then visit:

"Piled Higher and Deeper - Life (or the lack thereof) in Academia".

PHD Comics

A comic strip by Jorge Cham. In general every 2. or 3. day there is a new phd comic strip online and he hits absolutly the situation :)! Click here if you want to go directly to his most popular 200 comic strips! Enjoy!

p.s. have a visit in our optic labs!

Refractive Index Database

Who dont know this problem: you need something urgent but you have to spend two hours until you have found it. In optics, knowing the refractive index of a material at a certain wavelength could be such a problem. The long solution is to search a book or a paper which helps you to calculate the refractive index, the short solution...

...is going to RefractiveIndex.INFO

Refractive index database

created and maintained by Mikhail Polyanskiy. The Database is very extensive and includes:

Crystals/ Metals/ Liquids/ Gases/ Glasses/ Optical Glasses/ Plastics/ Liquid Crystals and even Metamaterials.

Simple choose the material and enter the desired wavelength. But you can do more as only calculating the refractive index. You can choose too from the optical property caculator things like:

reflection coefficient/ Abbe number/ Brewster´s angle/ critical angle or chromatic dispersion.

Simple things, but it save a lot of time. Enjoy!
