Laser for pump-probe spectroscopy at SLS 2.0

he same building, require the laser to be mobile between the two beamlines. For pump-probe spectroscopy, the laser is to provide tunable wavelengths spanning the ultraviolet (UV) to near-infrared (near-IR) range. The laser pulse duration needs to be shorter than the X-ray pulses, thus requiring puls

es in the tens of picoseconds (ps) or shorter timescale regime. Efficient excitation of the studied materials necessitates a high repetition rate in the range 40-131 kHz combined with a high pulse energy.
