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!

Infinity Mirror Illusion!
Time for a movie! It doesnt need much words for this one, have fun!

Encyclopedia of Laser Physics and Technology
The open access "Encyclopedia of Laser Physics and Technology" by Dr. Rüdiger Paschotta is well-known and very often consulted by researchers. I already have mention it briefly in an earlier post (literature search I) but i think it is really worth to draw your attention again on it by a separate post to this valuable and helpful encyclopedia.
Around 570 articles are listed, still growing. The navigation is clearly laid out. Most of the articles are very detailed, inlcuding references to scientific articles. They explain
"the physical principles and common techniques in laser technology, while also covering major areas of fiber-optic technology and nonlinear optics, and addressing supplementary topics like ultrashort pulses, optical communications, general optics, optoelectronics, and quantum optics."
quoted from the encyclopedia. During august 2010 around 160 000 page hits have been counted. If you havent yet known this encyclopedia, then click the link and take a minute for it. Test some keywords! You will not regret it. Have fun.

Companies & Photonics
If I ask you to write down how many companies you know working in the optic area, how many would it be? I think everyone knows Thorlabs and Newport, where most of us buy our optical components. And then... some other general well-known companies, some special companies working on your research topic, and then... i guess you know that there are much more companies.
There are several benefits for your research why to search once for other companies as to stay always at the same one:
You can browse by product/ service/ company name and region. The guide contains profiles and contact information for more than 4000 manufacturers and suppliers of photonics products and services worldwide. The page is clearly laid out and information are updated. Try it!
One more motivation why to know such a guide... if you are searching a job in the optics industry, you can find with the guide easily all the companies in your country ;).
There are several benefits for your research why to search once for other companies as to stay always at the same one:
- finding same product but cheaper (e.g. crystals, mechanical components, daily used things)
- better quality or performance (measurement devices)
- better support/ shorter delivering time (that is an important aspect)
- new products/ ideas for your research

Summer School!
In my opinion, every graduate student should at least have visited one summer school during his graduate studies. Why... because you benefit a lot from a summer school!
A summer school handles of a main topic and tries to bring together graduate students and young Post-docs from diverse range of fields relevant to the main topic. Lectures are normally given by leading researchers in the field. As a graduate student you will not only learn new things but you also have the chance to talk with the lectures in a relaxed atmosphere. In the postersession you can present your own work. A summer school goes between 1 and 2 weeks.
What I liked very much was to learn other graduate students from different places, working on the same/ similar project. Very nice for everyone are the social events during the school. Mostly you are going for sightseeing a day. And, in the evenings you are free to do what you want.
Normally, there is a small summer school fee but often you can apply for a scholarship which overtakes most of the fee. Summer school anouncements you can find everywhere... in journals (Photonics Spectra), on the blackboard of your department, but best thing is to ask simply your professor/ supervisor.
As an example for a summer school:
66th Scottish Universities Summer School in Physics
International Summer School in Ultrafast Nonlinear Optics 2010
Take the chance to visit a summer school!

Sunset in the Lab
Sunset in the lab, that´s how we named the first picture and I think you guess why ;).
We are focusing with a 1030nm beam in a YVO4 crystal generating "white light" which contains only near-infrared wavelengths from 600nm to around 1100nm. The blue light in the crystal originates from third harmonic generation.
The next picture shows stronger white light generation from 450nm to around 1400nm in a YAG crystal
Both pictures were taken in our lab by Thorsten Naeser and can be soon seen at the attoworld gallery.
If you want to know more about white light generation, then you should read following article: Femtosecond continuum generation in bulk laser host materials with sub-μJ pump pulses (journal access necessary).
Have fun!

Photonics in Spain: Open for Business
The latest (june/july 2010) euro photonics issue (included in photonics spectra) presents an article about the photonics in Spain:
A brief and very general overview of the situation of photonics development and research is given. ICFO, SECPhO and CLPU are mentioned. The article is nice to read and I guess especially interesting for our Spanish readers :) . Let´s hope future will show what the article says, namely: “Outlook is good”. Enjoy!
PS: the articles in the current photonics spectra issue are really interesting. Don’t forget, you can subscribe for free!
