Intense terahetz (THz) pulses induce a photoluminescence (PL) flash fromundoped high-quality GaAs/AlGaAs quantum wells under continuous wave laserexcitation. The number of excitons increases 10000-fold from that of the steadystate under only laser excitation. The THz electric field dependence and therelaxation dynamics of the PL flash intensity suggest that the strong electricfield of the THz pulse ionizes impurity states during the one-picosecond periodof the THz pulse and release carriers from a giant reservoir containingimpurity states in the AlGaAs layers.
