We employ several femtosecond laser systems, to generate the XUV pulses and tailored pump pulses for our experiments.
High harmonics can be generated by a KM Wyvern 1000, operating in the 3-12 kHz range or by a Coherent Astrella (3 kHz).
A second Coherent Astrella (operating at 6 kHz) is electronically synchronized to both the driver lasers and is equipped with a frequency-tuneable high energy TOPAS. Thanks to this system, very long delay time (up to about 0.16 ms ) can be studies, with a ps time resolution.
Finally a MHz laser source of harmonics up to 11 eV (KM Yperion) is available for high-energy resolution ARPES experiments.
