These modes have found many applications to date; however, they are limited to low power levels. It has thus become topical to consider amplification of such structured light modes. Here, we study the purity of the HOPS beams in a master oscillator power amplifier configuration using recently developed characterization tools through birefringent and non-birefringent amplifiers. We outline a general theory for this problem where we consider both gain and vector perspectives, and confirm our theory by experiment.enHigher order sphere Poincare beamsLaser beam shapingMaster Oscillator Power AmplifierPower AmplifierVector Quality FactorVector vortex beamsConference PresentationNaidoo, D., Sroor, H., Litvin, I., & Forbes, A.
