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:

Photonics in Spain: Open for Business (free access)

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!
