The FAB1-10 laser (ATTOLab Orme)

ATTOLab-Orme is a new infrastructure commissioned in 2016 for Ultra Fast studies at the femtosecond and Attosecond temporal scale. It combines the FAB1-10 laser, XUV femto / attosecond pulse generators based on high harmonic generation in gases and experimental stations for ultrafast dynamics in gas and solid phase.

The FAB1-10 laser

Based on the technique of chirped pulse amplification in titanium-sapphire, the FAB1-10 laser delivers at 1 kHz and 10 kHz ultrashort, CEP (Carrier Envelope Phase) stabilized pulses.

The FAB1-10 laser

The FAB1-10 laser comprises a "front-end" consisting of the oscillator, the stretcher and 3 preamplifier stages operating at 10 kHz. The second and third preamplifier stages are based on a 2-cristal design that assures an excellent spatial profile even when high pump energies are used [Golinelli et al., OPTICS LETTERS 42 (12), 2326 (2017)]. The power at the front end output is 7.5W (750μJ per pulse).
The "front-end" seeds 2 power amplifiers operating respectively at 1 kHz (FAB1 channel) and 10 kHz (FAB10 channel). The power obtained after compression is 15W for FAB1 and 20W for FAB10 with sub 25fs pulse duration.
