18. The generated laser pulses have rectangular shape with fall and rise times of ∼1 ns. The "zero" of the time scale is defined by the end of the laser pulse. Negative values correspond to the measurements taken under laser illumination. For the estimation of the decay time we take only experimental points recorded after the laser pulse.
