Interference of axially-shifted Laguerre-Gaussian beams and their interaction with atoms

K. Koksala, V. E. Lembessisb, J. Yuanc +1

Counter-propagating co-axial Laguerre-Gaussian (LG) beams are considered, not in the familiar scenario where the focal planes coincide at $z=0$, but when they are separated by a fi…
