Purity of vector vortex beams through a birefringent amplifier. Physical Review Applied, vol 9, pp 1-92331-7019https://journals.aps.org/prapplied/abstract/10.1103/PhysRevApplied.9.044010http://hdl.handle.net/10204/10565Copyright: 2018 American Physical SocietyCreating high-quality vector vortex (VV) beams is possible with a myriad of techniques at low power, and while a few studies have produced such beams at high power, none have considered the impact of amplification on the vector purity. Here we employ tools to study the amplification of VV beams and, in particular, the purity of such modes. We outline a versatile toolbox for such investigations and demonstrate its use in the general case of VV beams through a birefringent gain medium. Intriguingly, we show that it is possible to enhance the purity of such beams during amplification, paving the way for high-brightness VV beams, a requirement for their use in high-power applications such as optical communication and laser-enabled manufacturing.enVector vortex beamsVector purityArticleSroor, H., Lisa, N., Naidoo, D., Litvin, I., & Forbes, A.
