Signal processing in electronic devices is in the THz regime. Here the authors measure NIR lightwave-field-induced multiple dipole oscillations in Cr:Al2O3 in the time domain reaching PHz scale by using an isolated attosecond pulse and this method shows potential for higher speed signal processing.
