Design of a fast speckle wavemeter with optical processing
Lucas Rodrigo Mendicino, Christian Tomás Schmiegelow
We present a design concept for a speckle based wavemeter that combines high spectral resolution and fast response times. Our device uses a fixed disperse medium with small coheren…
The paraxial approximation fails to describe the interaction of atoms with general vortex light fields
Guillermo F. Quinteiro, Christian T. Schmiegelow, Ferdinand Schmidt-Kaler
Neglecting the electric field component along the light's propagation direction is a common practice, known as paraxial approximation. However, experimental evidence and theory on…
Bessel beams revisited: a generalized scheme to derive optical vortices
G. F. Quinteiro, C. T. Schmiegelow, D. E. Reiter +1
The electromagnetic field of optical vortices is in most cases derived from vector and scalar potentials using either a procedure based on the Lorenz or the Coulomb gauge. The form…
Twisted-ligth--ion interaction: the role of longitudinal fields
Guillermo F. Quinteiro, Ferdinand Schmidt-Kaler, Christian T. Schmiegelow
The propagation of light beams is well described using the paraxial approximation, where field components along the propagation direction are usually neglected. For strongly inhomo…
