Abstract

Different behaviors of isophase curves presenting zero values of the real and imaginary parts of the transverse varying scalar electric field of a laser are presented. We illustrate how phase singularities (isophase crossings) might evolve by variation of the amplitudes of superposed Laguerre-Gaussian cavity modes. These show the formation of closed loops and kinks. Numerical simulations of the transverse pattern dynamics give similar forms of phase singularity motion and evolution.
