Limits of measuring vortex beam strength

Researchers analyzed practical fractional vortex beams in simulations to understand limits of measuring their topological charge strength accurately, finding the measurement depends on beam waist size. They introduced a "strength staircase" concept showing strength transitions differ from idealized theories.
