Lasing action in air induced by ultrafast laser filamentation

The backscattered fluorescence of nitrogen from long filaments generated by intense ultrafast Ti-sapphire laser pulses propagating in air is studied. It shows an exponential increase with increasing filament length, indicating amplified spontaneous emission (ASE).
