The digital holograms were encoded with an amplitude ring mask, which contained absorption rings that match the p-zeros of the Laguerre polynomial. We demonstrate the generation of high-quality LGp,0 modes with a mode volume that is directly proportional to the mode order, p. This work demonstrates the possible of using the digital laser as a tool for simulating optical elements that will be used in pursuing high brightness lasers.enAttribution-NoDerivs 3.0 United StatesLasersLaser resonatorsSpatial light modulatorsHolographic optical elementsLaser beam shapingLaser beam characterizationArticleBell, T., & Ngcobo, S.
