Abstract :
Summary form only given. The authors theoretical and experimental results demonstrate that the nonlinear Schrodinger equation (NLSE), which includes the effects of self-steepening and space-time focusing, gives an accurate description of the pulse-splitting dynamics in the self focusing of femtosecond laser pulses.
