APE (standing for Angewandte Physik & Elektronik GmbH, a german company in Berlin) has a nice small (and free) wavelength converter on their homepage. It allows you to directly calculate the sum frequency and difference frequency generation, the wavelengths relations in an optical parameteric oscillator (OPO) as well as in coherent anti-stokes Raman scattering (CARS) spectroscopy. Furtermore, the conversion between wavelength, wavenumber, and frequency as well as different characterizations of pulses (dispersion) can be calculated.
The calculator page is in english and very userfriendly. Enjoy.

Prism Awards 2011
The finalists for the prism awards for photonic innovations by the SPIE has been anounced:
Finalists Prism Awards
Take the time to look at the finalists in the 9 different categories. The awards will be presented at the next SPIE Photonics West in January.

Video Showing the Inside of a Ti:Sa Laser
I was quite surprised to find such a video showing in detail a titanium saphire laser from a company. Let's see how long it stays at youtube ;) .
Have fun watching it!

SWAMP OPTICS... & lectures
The ones of you working in the field of ultrafast lasers know what I mean with Swamp Optics, for the other ones it is a company for ultrashor laser pulse measurements. SWAMP Optics was founded by Rick Trebino, the inventor of FROG and GRENOUILLE (which is french and means frog). As you imagine, FROG and GRENOUILLE stands for some types of pulse measurement devices... and their strongest competitor is the SPIDER. Well well... Recently I got aware that SWAMP also stands for something, namely "simply wonderful apparatus for measuring pulses"...
Aside from that, the homepage includes a real good choice of tutorials about pulse measurement devices: Swamp optics Tutorials and also the lectures from Prof. Trebino are available: lecture files. It is really worth to read it. Have fun!

Seen in twitter.
"We don't allow faster than light neutrinos in here" said the bartender. A neutrino walks into a bar."
Jokes are coming out in reaction to the announcement of CERN that they have found neutrinos that travel faster than the speed of light. Einstein theories have been challenged several times, but the theory always proved to be right, so we'll wait a bot, before changing our courses.

InTech - Open access publisher of Scientific Books and Journals
Founded in 2004, InTech is a open access book (and some journals) publisher covering the field of science and technology. Since then, they have published already over 550 books with over 2.5 millions of downloads (counting the chapter downloads). In 2010 its publishing program was expanded into the field of medecine.
Concerning the field of Optics and Lasers, 16 books have been published so far. Although the titles of the books sounds general, the chapters are already dedicated to a specific research topic, which makes it not very suitable for non-expert who are looking for an overview or introduction. However, if you work in the same field, it is probably worth to have a look into it.

Sam's Laser FAQ
The homepage of "Sam's Laser FAQ" looks on the first moment very old and strange but actually, it is a real treasure about lasers. Sam's Laser FAQ exist already since 1994 by Samuel M. Goldwasser and is updated until today. One has to understand this page as "a practical guide to lasers for experimenters and hobbyists". It is a huge page and the navigation is a bit unusual but nevertheless it is worth to spend some time on it. Have a look on the "comprehensive table of contents". There are tons of chapters and sections as well as many many pictures, covering the scope from different types of lasers to possible experiments to do by oneself. Actually, there is a certain change that you find your laser which you uses in the lab and how you can repair it ;). What is missing on the page is a section about pulsed lasers, especially fs or ps laser as well as amplifications schemes. However, Sam's Laser FAQ addresses mainly hobbiest and for them it is a true treasure... and many hearts of scientists will jump faster if they see the pictures ;).
