A family of special solutions of the paraxially pulsed wave equation is presented in closed form by use of the Fourier-transform method. These special solutions have the negative-power-function forms of a simple complex temporal–spatial beam parameter <i>P</i>. The imaginary part and the real part of the parameter <i>P</i> explicitly reveal the time delay and the pulse broadening, respectively. These pulsed negative-power-function light beams are used analytically to expand those isodiffracting pulsed beams.
