A novel digital laser setup with two controllable phase boundaries can generate complex structured beams. Experiments confirm the new configuration can generate vortex beams with controllable over both topological charge and intensity profiles. Not only vortex beams, but this cavity can also produce all kind of nondiffracting beam, including the Parabolic-Gauss beam, which was previously unattainable directly from laser cavities. This innovative digital laser configuration represents a versatile option for customizable structured beam laser facilitating wide-ranging applications.
