Propagation-Invariant Off-Axis Elliptic Gaussian Beams with the Orbital Angular Momentum
We studied paraxial light beams, obtained by a continuous superposition of off-axis Gaussian beams with their phases chosen so that the whole superposition is invariant to free-space propagation, i.e., does not change its transverse intensity shape. Solving a system of five nonlinear equations for s...
