The PLFA facility

PLFA, one of the most intense titanium-sapphire kHz laser in Europe, provides 13mJ, 32fs pulses at 1kHz (peak power of 0.4TW) for studying laser-matter interaction at high intensity. PLFA also features an infrared OPA (from Light Conversion) that delivers infrared pulses in the 1150-1600 nm range with a pulse duration estimated at 50-60 fs ; the output energy is typically 2mJ for 9 mJ of pump power at 800nm with an output stability of about 3%.




Tunability of the OPA on PLFA
The tunability of the signal extends from 1150 to 1600 nm.



A permanent workstation is available for gas phase studies using ultrashort (fs to as) XUV pulses combined with intense IR/mid-IR fs pulses with (actively-controlled) attosecond precision for multiphoton coherent excitation and/or pump-probe investigations. It includes two delay lines allowing delivery of 3 beams with attosecond-controlled delays, a harmonic generation chamber providing trains of XUV attosecond pulses, an XUV spectrometer and a 2m magnetic bottle electron spectrometer (MBES). It is used and operated by the LYDIL/ATTO group.

The PLFA laser will be upgraded in 2015 into the FAB1-10 facility that will provide 2 lines of CEP stabilised high energy pulses (15 mJ @ 1 kHz and 2 mJ @ 10kHz) with ultrashort pulse duration (<25 fs in 2015 then ≈15 fs in 2017); FAB1-10 will be connected to XUV beamlines and a complete line of workstations to study electron dynamics in atoms, molecules and solids with sub-femtosecond resolution. These research programmes will be carried out within the EQUIPEX ATTOLAB.
