Abstract
In this paper we experimentally demonstrate a simple laser cavity that produces spatial tuneable laser modes from a Gaussian beam to a Flat-top beam and a Donut-beam. The laser cavity contains an opaque ring and an adjustable circular aperture that could be varied and thus allows for tuneability of the cavity without it being realigned. A digital laser with an intra-cavity spatial light modulator is used to demonstrate and confirm the predicated properties of the resonator.
