Rydberg states of excitons in Cu2O are known to interact strongly with other carriers in their surrounding such as other excitons, free charge carriers and static charged impurities. In cw- experiments, discriminating the individual processes is notoriously challenging. Here, we use a time-resolved two-color pump-probe setup and investigate the temporal evolution of Rydberg excitons with a resolution of 15 ns. The dynamic response of the Rydberg system to pump pulses with different energies is measured and analyzed. <p>
A thorough discussion of the analysis is given in the related publication. <p>

The files include all measured time-resolved transients for a probe laser resonant with the 10P exciton at varying pump laser energies and powers. The first column contains the time-axis. The following columns contain the change in absorption of the probe laser, measured as - \Delta \alpha, in 1/mm for different pump powers in an increasing order. The pump power for each column is given in the third row. <p>
File naming convention: <p>
"Pr10@0.2uW": Probe laser resonant with 10P at 0.2 uW laserpower. The pump laser is set to resonances 14P, 9P, the phonon background or below the resonance of 1S, resp. "pumppowerseries" indicates that a whole series of different pump laser powers is stored in the files.
