Monika Bahl, P. SenthilkumaranSingular beams have circulating energy components. When such beams are focused by low numerical aperture systems suffering from astigmatic aberration, these circulating energy components get modified. The phase gradient introduced by this type of aberration splits the higher charge vortices. The ... [J. Opt. Soc. Am. A 31, 2046-2054 (2014)]
