5.1 fs pulses by filamentation — future prospective of self-compression to one optical cycle
Intense 5.1-fs pulses with a spectral range covering more than 600 THz were generated through filamentation in argon. Numerical simulations show that filamentation in a pressure gradient leads to a self-compression of the input pulses down to one optical cycle.
