Abstract

We report measurements concerning the propagation of femtosecond laser pulses in fused silica with a wavelength at 1.9 μm falling in the negative group velocity dispersion region. Under sub-GW excitation power, stable filaments are observed over several cm showing the emergence of nonspreading pulse...
