The present study deals with the propagation of an ultrashort narrow laser beam in a parabolic plasma channel. The effect of transverse ponderomotive nonlinearity on the propagation characteristics of the laser beam is analyzed. Using the variational technique, coupled equations describing the evolution of pulse length and spot size are obtained. The variation of intensity, of mismatched and matched laser pulses, with propagation distance is graphically depicted.
