Abstract
Femtosecond space-time coupling effects in dispersive nonlinear media are investigated by a simple The applicability of the method is verifi ed by comparison with earlier numerical simulations. New results are p resented for astigmatic beams as well as for negative dispersion. The position of the beam waist in the material changes the collapse thresh old. For astigmatic beams, collapse is prevented for pulse durations s horter than a critical value. (C) 1996 Optical Society of America
