(a) Envelope of the driving field \(\mathscr {E}\) (black) and generated signal \(E_\text {signal}\) (blue) as functions of time at the end of the sample (\(z=L\)) for \(\gamma _\text {se}=0.75\) Hz, \(\gamma _\text {coll} =65\) kHz, and \(\delta =0\). (b) The signal \(E_\text {signal}\) in the spatial domain at \(t=30\) ns. The gray rectangle represents the sample with the active medium (between 0 and 0.53 m).
