Abstract

For the azimuthally varying complex-argument Laguerre-Gauss beams, the Fourier integral representation is used to obtain the time-averaged power and the transport equation for the mean-squared beam width. From the coefficients in the transport equation, two propagation parameters are derived and compared with the previous treatments.
