In France, ultrafast laser specialist Amplitude Systèmes of Bordeaux and Laboratoire Charles Fabry of Institut d'Optique in Palaiseau have established a joint research laboratory that will support 10 researchers working on high-performance lasers. Called DEFI, the new lab is based at the institute and will focus on diode-pumped ultrafast lasers. The team will work on both emerging concepts and prototype laser development for the next generation of ultrafast sources. Amplitude has worked on ytterbium ultrafast lasers with Laboratoire Charles Fabry since 2006, a collaboration that has resulted in technologies including the shortest duration from oscillators and regenerative amplifiers and in sub-100-fs high-energy fiber lasers.
