MBI - Attosecond pump-probe with coincidence detection
Combination of carrier-envelope phase-stable few-cycle VIS-IR pulses and attosecond XUV pulses (trains or single pulses) in pump-probe configuration with sub-50 as resolution. Detection of photoelectrons and photoions in coincidence upon photo-ionization, utilizing a reaction microscope.

Additional Lightsources
100 kHz NIR OPCPA
Laser type
OPCPA. The main source is a noncollinear optical parametric chirped pulse amplifier. It delivers 0.19 mJ of energy per pulse at a repetition rate of 100 kHz (19 W of average power). The polarization of this source, without any modification is linear. The spectrum covers the range 670-1050 nm. The pulse duration is 7 fs. Pulses are Carrier-Envelope Phase-Stable

Other polarisation
The polarization can be adjusted rather arbitrarily, although pulse compression needs to be readjusted in that case

Post-compressed 100 kHz OPCPA
Laser type
OPCPA+nonlinear pulse compression stage. Polarization can be controlled arbitrarily. Pulse duration can be pushed to a lower limit of 3.2 fs (limited by dispersion compensation mirrors) and in general is <4fs. Nonlinear spectral broadening is done either by propagation of intense OPCPA pulses in a gas-filled hollow-core fiber, or through thin quartz plates. Pulses are Carrier-Envelope Phase-Stable
