Editorial

Welcome to Volume 9 of Optics Express. I want to call everyone's attention to a breakthrough that occurred in Volume 8. After nagging authors for a year or more, my efforts finally paid off (you can see I want to take credit for this!) in the publication of an article in which an audio voice-over was used to provide captioning of movies. This was handled extremely well by the authors, and enhanced greatly the effect of the video presentation. I congratulate them for taking up the "audio challenge" laid down in the very first issue of Optics Express by the article of West and Stroud. The recent audio-enhanced article was "Phase-space analysis of double ionization" by Manfred Lein, Volker Engel and E. Gross. It appeared on page 411 (Vol. 8) as part of an excellent Focus Issue on Laser-Induced Multiple Ionization coordinated by Wilhelm Becker and Mikhail Fedorov.
