Abstract

We show that optical vortices and $J_{0}$ Bessel-like beams can be generated via traveling-wave linear parametric amplification of the quantum noise, in the absence of external seeding or resonator feedback. The shot-to-shot fluctuations in the topological charge of the amplified signal are driven by the quantum-noise seed.
