  We consider optical properties of Hypergeometric-Gaussian beam compositions
with spiral-like intensity and phase distributions that were called the spiroid
beams. Their orbital angular momentum as a function of a fractional-order
topological charge has a chain of supper-pulses (bursts and dips).The form of
the supper-pulses can be controlled by the spiral parameters. Such a phenomenon
can be used in optical switches and triggers for optical devices and
communication systems.
