Spatial amplitude and phase modulation using commercial twisted nematic LCDs
E. G. van Putten, I. M. Vellekoop, A. P. Mosk
We present a method for full spatial phase and amplitude control of a laser beam using a twisted nematic liquid crystal display combined with a spatial filter. By spatial filtering…
Phase control algorithms for focusing light through turbid media
I. M. Vellekoop, A. P. Mosk
Light propagation in materials with microscopic inhomogeneities is affected by scattering. In scattering materials, such as powders, disordered metamaterials or biological tissue,…
Relaxation oscillations in long-pulsed random lasers
Karen L. van der Molen, Allard P. Mosk, Ad Lagendijk
We have measured the evolution of the light intensity of a random laser during a nanosecond pump pulse. Relaxation oscillations in a titania random laser were observed in the time…
Trapping of Rb atoms by ac electric fields
Sophie Schlunk, Adela Marian, Peter Geng +3
We demonstrate trapping of an ultracold gas of neutral atoms in a macroscopic ac electric trap. Three-dimensional confinement is obtained by switching between two saddle-point conf…
